Download or read book Electronic Transport in Two dimensional Transition Metal Dichalcogenide MoS2 Under Photoexcitation written by Phuong Xuan Nguyen and published by . This book was released on 2019 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: We investigate the formation and transport behaviors of photo-excited carriers in two dimensional transition metal dichalcogenide MoS2 under intense polarized continuous-wave excitation. By opto-electrical measurement and contactless terahertz time-domain spectroscopy, involving a dc electric field and a weak broadband terahertz as probe fields, respectively, we characterize the material's electrical and photo-responses. Circularly polarized light plays an important role in studying the valley-specific behaviors by breaking time reversal symmetry and creating a net valley polarization. In the THz TDS approach, we obtained important parameters like carrier concentrations, and carrier scattering times through fitting with a modified Drude model. Especially, the formation of negatively charged trion, a quasiparticle consisting of two electrons and one hole in MoS2, and the steady-state electron-trion dynamics made significant contributions to the material photoconductivities in the THz regime. On the other hand, under a dc electric probe field, where the trion and exciton formations are suppressed, we look at the valley Hall effect. This anomalous Hall voltage is a result of the intrinsic strong spin-orbit coupling and the lack of inversion symmetry in 2D MoS2, in addition to time reversal breaking. The valley Hall effect and its corresponding photo-conductivities can be quantitatively explained by the quantum kinetic Liouville equation, using the massive Dirac Hamiltonian model of MoS2. The analytical expressions for the longitudinal and Hall conductivity are obtained by the density matrix approach underrotating wave approximation. A good understanding of carrier formation and transport parameters are instrumental for the development of TMD-based optoelectronics, spin- and valley-tronics in the future.

This book was released on 2019 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atomically layered transitional metal dichalcogenides (TMDs) manifest many fascinating properties such as atomic-scale thickness, favorable mechanical, electronic and optoelectronic properties and strong spin-orbit coupling. In terms of electronic properties, the TMDs range from insulating or semiconducting to metallic or semi-metallic. Some of them also exhibit exotic electronic phases such as charge density waves and superconductivity. Recent advances in nano-materials characterization and device fabrication, in particular, fabrication of high quality van der Waals heterostructures, have boosted studies on two-dimensional layers of thin TMDs for purpose of both fundamental research and industrial applications. In this thesis, I present a series of experiments investigating electronic and optoelectronic properties of semiconducting TMDs MoS2 and WSe2. I also demonstrate technical advances in fabrication of van der Waals heterostructures, which enables high-quality encapsulated thin TMDs devices with ionic liquid introduced as electrolyte. I further show that phase transitions in superconducting TMDs such as 2H-TaS2 can be greatly impacted by dimensionality reduction. A substantial enhancement of superconducting T, and a suppression of the CDW transition are observed in 2H-TaS2 in the 2D limit. At last, I present a machine learning algorithm to realize pixel-wise classification on laboratory acquired images of various 2D materials, which might open up new opportunities for full automation of nano-material search and device fabrication.
