Available in PDF, EPUB and Kindle. Book excerpt: Metal halide perovskites have demonstrated tremendous promising electronic and optoelectronic properties that make them appealing in various device applications. Even though surprising improvement has been achieved during the past few years in polycrystalline perovskite-based devices, problems of their intrinsic high defects level, existence of grain boundaries, strong ion migration rates, and poor stabilities can heavily hinder the further development of polycrystalline perovskite electronics and their realistic applications. In contrast, their single-crystal counterpart is well-studied to have much better crystalline qualities, enhanced electrical properties, and excellent material stabilities, making them intriguing for reaching advanced device performance and realistic applications. However, the development of single-crystal perovskite electronic devices is still in its infancy; even the controlling over dimensions, scalabilities, morphologies, and compositions on single-crystal perovskites, are still challenging. Based on those motivations, this research aims to develop a general platform for realizing single-crystal metal halide perovskites electronics from the material growth to the thin-film device fabrication. The solution-based chemical epitaxy method, the lithography and etching approaches, and the transfer printing processes will be combined together to form this fabrication protocol, which is also compatible with the conventional semiconductor processes. In Chapter One, the basic properties of metal halide perovskites and the current problems presented in this field will be introduced and discussed. In Chapter Two, an epitaxial growth method of metal halide perovskite will be introduced. Our work presents the first controllable growth of single-crystal perovskites with different dimensions, morphologies, crystalline orientations, and compositions. In Chapter Three, a general fabrication process for metal halide single-crystal perovskite electronic integrations will be introduced. Our work presents a reliable approach to integrate metal halide single-crystal perovskite into electronics/microelectronics. In Chapter Four, a general strategy for fabricating flexible metal halide single-crystal perovskite electronics will be introduced. Our work presents the first realization of flexible single-crystal perovskite electronics/micro-electronics, which paves the way for realizing high-performance single-crystal metal halide perovskites wearable electronics.

This book was released on 2020 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: As an emerging class of semiconductors, metal halide perovskites have demonstrated tremendous potential in various applications, including photovoltaic solar cells, light-emitting diodes, photodetection, and many other electronic devices. While most of these perovskite electronic devices have adopted polycrystalline perovskite thin films, problems of polycrystalline thin films like the high density of grain boundaries and defects, low stability can hinder the further performance enhancement of perovskite electronic devices. Comparing with their polycrystalline counterpart, single-crystal perovskites provide opportunities in solving such problems. Not only can they provide enhanced crystalline quality and excellent material stability, but also the possibility to alter the electronic properties of perovskites by lattice-mismatch-induced strain. Yet the development of single-crystal perovskite electronic devices is still in its infancy due to the low controllability over the growth of single-crystal perovskite nano/micro-structures and the incompatibility with the conventional semiconductor fabrication protocol. This research aims to develop a platform for growing high-quality single-crystal metal halide perovskite nano/micro-structures using controllable chemical homo/heteroepitaxial growth and fabricating high-performance single-crystal-perovskite-based electronic devices with the conventional semiconductor fabrication protocols. In Chapter One, the basic properties of metal halide perovskites and the current problems presented in the polycrystalline perovskite thin films will be introduced and discussed. In Chapter Two, controllable homoepitaxial growth of metal halide perovskite micro-arrays will be introduced. Our work presents the first controllable growth of large-area single-crystal perovskite microarrays with different sizes, morphologies, crystalline orientations, and patterned structures. In Chapter Three, controllable strain engineering of single-crystal metal halide perovskite thin films by heteroepitaxial-growth-induced lattice mismatch will be introduced. Our work presents the first controllable strain engineering in metal halide perovskite family. In Chapter Four, epitaxial stabilization induced by the chemically epitaxial strain growth will be introduced. Our strategy provides insights into structurally stabilizing the metastable metal halide perovskite family. Our understanding of the controllable epitaxial growth of metal halide perovskites paves the way for next-generation single-crystal metal halide perovskites electronic devices.

Available in PDF, EPUB and Kindle. Book excerpt: Organic perovskites have been growing in the field of organic electronics, and lately field-effect transistors with single-crystalline perovskites have received more attention, because they should have ideal field-effect mobility and new crystal growth techniques have made them easier to synthesize. This research works to improve the reproducibility of the single-crystal growth as well as pattern the perovskite single crystals for better device reproducibility. We were successful in patterning the crystal growth, using silicon chips patterned via photolithography, and a custom-made clamp to even the pressure applied to the substrates. However, improved contact between the substrates and better control over the pressure applied during the annealing process is needed to improve the quality of the patterned crystal growth.
Download or read book High pressure Single crystal Structures of 3D Lead halide Hybrid Perovskites and Pressure Effects on Their Electronic and Optical Properties written by and published by . This book was released on 2016 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here, we report the first high-pressure single-crystal structures of hybrid perovskites. The crystalline semiconductors (MA)PbX3 (MA = CH3NH3+, X = Br- or I- ) afford us the rare opportunity of understanding how compression modulates their structures and thereby their optoelectronic properties. Using atomic coordinates obtained from high-pressure single-crystal X-ray diffraction we track the perovskites' precise structural evolution upon compression. These structural changes correlate well with pressure-dependent single-crystal photoluminescence (PL) spectra and high-pressure bandgaps derived from density functional theory. We further observe dramatic piezochromism where the solids become lighter in color and then transition to opaque black with compression. Indeed, electronic conductivity measurements of (MA)PbI3 obtained within a diamond-anvil cell show that the material's resistivity decreases by 3 orders of magnitude between 0 and 51 GPa. The activation energy for conduction at 51 GPa is only 13.2(3) meV, suggesting that the perovskite is approaching a metallic state. Furthermore, the pressure response of mixed-halide perovskites shows new luminescent states that emerge at elevated pressures. We recently reported that the perovskites (MA)Pb(BrxI1-x)3 (0.2
