Band Structure Modulation in Ternary-Based InAs/ AlAs1-xSbx /InAs1-xSbx Superlattices
Arash Dehzangi, Jiakai Li
This study demonstrates an overall view of recent quantum mechanical based modeling effort using empirical tight-binding method to expand the ability of calculation of electronic b…
A Comprehensive Study of Charge-Carrier Mobility in Double Lateral-Gate Silicon Junctionless Transistors
Farhad Larki, Arash Dehzangi
We give in depth overview of charge-carrier mobility in p-type silicon double lateral-gate junctionless transistors (DLGJLT) through a mix of computer simulations and experimental…
Quantum Mechanical Approach for Modeling of Ternary Based Strained-Layer Superlattice
Arash Dehzangi, Jiakai Li
Ternary-based InAs/InAs1-xSbx Strained-Layer Superlattice (SLS)material with type-II band alignment belongs to the 6.1 A family with reasonably small lattice mismatch with GaSb sub…
Multiband strain balanced superlattice material system for third generation infrared detectors
Arash Dehzangi
Recent increasing interest in strain balanced Type-II superlattices material causing close attention from industry. Tremendous investment was drawn toward establishing strain balan…
Ion-Implantation as Pixel Isolation for Fabrication of Planar Strain-Balanced Antimony-based Superlattice Infrared Photodetectors
Arash Dehzangi
Strained layer superlattice (SLS) material system is a dynamic and relatively new material for infrared detection. Large format, small-pitch and low-cost focal plane arrays (FPAs)…
Short wavelength infrared avalanche photodetector using Sb-based strained layer superlattice
Arash Dehzangi, Jiakai Li, Manijeh Razeghi
We demonstrate a low noise short wavelength infrared (SWIR) Sb based type II superlattice (T2SL) avalanche photodiodes (APD). The SWIR GaSb/(AlAsSb/GaSb) APD structure was designed…
