Book excerpt: This project concentrates on the design, fabrication and characterization of compound semiconductor photodetectors in various material systems operating at near-IR wavelengths. We utilize resonant cavity enhanced (RCE) detection scheme to optimize speed and responsivity of photodetectors. It is also desirable to combine multiple functions in a single photodetector structure. In addition to wavelength selectivity of RCE photodetectors, we have demonstrated that RCE detectors vertically integrated with one-pass detectors can be used for polarization sensing. We have fabricated RCE photodetectors working at 800 to 900 nm wavelength range with record bandwidth-efficiency products. RCE Schottky photodiodes with 100 GHz bandwidth, p-i-n photodiodes with 50 GHz bandwidth and near-unity quantum efficiency have been demonstrated.

Book excerpt: The goal of the proposed research is to develop new photodetectors that are capable of high power operation at high frequencies for microwave fiber optic link applications. Conventional high frequency photodetectors have low saturation power because of the small absorption volume required to reduce transit time and parasitic capacitance. We have proposed a novel velocity-matched distributed photodetector (VMDP) that can achieve high bandwidth and high saturation power simultaneously. During the performance period, we have successfully demonstrated three generations of long-wavelength VMDP's operating at 1.3 and 1.55 mm fiber optic communication wavelengths. The VMDP consisting of metal-semiconductor-metal (MSM) photodiodes serially connected by an optical core optical waveguide and an coplanar strip microwave transmission line that is velocity-matched to the optical waveguide. The MSM phodiodes have been patterned by both optical and e-beam lithography. We have demonstrated a bandwidth of 18 GHz and a quantum efficiency of 0.42 A/W. The maximum linear photocurrent measured is 12 mA. The distribution of photocurrents inside the VMDP has also been measured using a novel split contact structure. Test patterns on nanoscale MSM photodiodes show a bandwidth> 50 GHz (measurement limit). The research results achieved in this program has been transferred to TRW, Focused Research, and BAE. TRW has provided additional funding for transfer the technology to TRW. Focused Research has obtained a Phase II SBIR to commercialize VMDP.

Book excerpt: This is the third volume in a series of books on selected topics in Nanoscale Science and Technology based on lectures given at the well-known Istituto Nazionale di Fisica Nucleare (INFN) schools of the same name. The present set of notes stems in particular from the participation and dedication of prestigious lecturers, such as Nunzio Motta, Fulvia Patella, Alexandr Toropov, and Anna Sgarlata. All lectures have been carefully edited and reworked, taking into account extensive follow-up discussions. A tutorial lecture by Motta et al. presents the analysis of the Poly(3-hexylthiophene) self assembly on carbon nanotubes and discusses how the interaction between the two materials forms a new hybrid nanostructure, with potential application to future solar cells technology. In their contribution, Patella et al. review quantum dots of III-V compounds, which offer appealing perspectives for more sophisticated applications in new generation devices such as single-photon emitters for nano-photonics and quantum computing. Focusing on self-assembled quantum dots, the chapter by Alexandr Toropov et al. provides a comprehensive review of some important aspects in the formation of quantum dots and presents the results of the authors’ extensive investigation of the features of droplet epitaxy. The fourth contribution, by Sgarlata et al., focuses on recent progress toward controlled growth of self-assembled nanostructures, dealing with the shaping, ordering and localization in Ge/Si heteroepitaxy and reviewing recent results on the self-organization of Ge nanostructures at Si surfaces.

Available in PDF, EPUB and Kindle. Book excerpt: 2D Materials for Infrared and Terahertz Detectors provides an overview of the performance of emerging detector materials, while also offering, for the first time, a comparison with traditional materials used in the fabrication of infrared and terahertz detectors. Since the discovery of graphene, its applications to electronic and optoelectronic devices have been intensively researched. The extraordinary electronic and optical properties allow graphene and other 2D materials to be promising candidates for infrared (IR) and terahertz (THz) photodetectors, and yet it appears that the development of new detectors using these materials is still secondary to those using traditional materials. This book explores this phenomenon, as well as the advantages and disadvantages of using 2D materials. Special attention is directed toward the identification of the most-effective hybrid 2D materials in infrared and terahertz detectors, as well as future trends.
