The advent of nanophotonics allows devising and fabricating optical antenna as the advanced optical structures that can enhance light–matter interaction in quantum structures such as quantum wells. Improving infrared photodetector performance is discussed theoretically in this paper. We also investigate our recent demonstration of optical antenna integrated on quantum well infrared photodetecto...

We study the optical transition between bound-to-continuum states in InGaAs/GaAs quantum well infrared photodetector (QWIP) by analyzing two possible boundary conditions for the continuum states. InGaAs/GaAs QWIP differs from the GaAs/AlGaAs QWIP in many aspects. Comparing running wave function and Bloch wave function with experimental results, we find that Bloch wave function is the much more ...

In this letter, we present a comparative study of positive bias temperature instability (PBTI) reliability in InxGa1−xAs FinFET with varying Indium (x = 0.53, 0.70) percentage and quantization [bulk, quantum well (QW)]. Due to lower effective transport mass and higher injection velocity, In0.7Ga0.3As QW FinFET provides better performance than In0.53Ga0.47As bulk FinFET. However, stronger quanti...

We consider the problem of recovering the coeecient q(x) in the equation u t = u ? qu from boundary observations. Uniqueness of q based on knowledge of thèNeumann 7 !Dirichlet response operator' is shown as an implication of (known) corresponding results concerning the inverse problem for the corresponding hyperbolic equation w tt = w ? qw. This is then reduced to use of the response to a singl...
