Dielectric Resonator Antenna Coupled Antimonide-Based Detectors (DRACAD) For the Infrared
Jordan Budhu, Nicole Pfiester, Kwong-Kit Choi +4
In an infrared photodetector, noise current (dark current) is generated throughout the volume of the detector. Reducing the volume will reduce dark current, but the corresponding s…
Theoretical study of strain-dependent optical absorption in Stranski-Krastanov grown InAs/InGaAs/GaAs/AlGaAs quantum dots
Tarek Ameen, Hesameddin Ilatikhameneh, Yuling Hsueh +10
A detailed theoretical study of the optical absorption in self-assembled quantum dots is presented in this paper. A rigorous atomistic strain model as well as a sophisticated elect…
Quantum Size Effects on the Chemical Sensing Performance of Two-Dimensional Semiconductors
Junghyo Nah, S. Bala Kumar, Hui Fang +6
We investigate the role of quantum confinement on the performance of gas sensors based on two-dimensional InAs membranes. Pd-decorated InAs membranes configured as H2 sensors are s…
Highly Quantum-Confined InAs Nanoscale Membranes
Kuniharu Takei, Hui Fang, Bala Kumar +10
Nanoscale size-effects drastically alter the fundamental properties of semiconductors. Here, we investigate the dominant role of quantum confinement in the field-effect device prop…
Ultrathin compound semiconductor on insulator layers for high performance nanoscale transistors
Hyunhyub Ko, Kuniharu Takei, Rehan Kapadia +13
Over the past several years, the inherent scaling limitations of electron devices have fueled the exploration of high carrier mobility semiconductors as a Si replacement to further…
Design of plasmonic photonic crystal resonant cavities for polarization sensitive infrared photodetectors
Jessie Rosenberg, Rajeev V. Shenoi, Sanjay Krishna +1
We design a polarization-sensitive resonator for use in midinfrared photodetectors, utilizing a photonic crystal cavity and a single or double-metal plasmonic waveguide to achieve…
