We describe the use of optically levitated microspheres as test masses in experiments aimed at reaching and potentially exceeding the standard quantum limit for position measurements. Optically levitated microspheres have low mass and are essentially free of suspension thermal noise, making them well suited for reaching the quantum regime. Table-top experiments using microspheres can bridge the...
Quantum well (QW) structures are formed in nanometer-thickness-scale semiconductors with different bandgaps sandwiched configurations and can offer a wide variety of advantages as active layers for optoelectronic devices, e.g., laser diodes, light emit photodetectors, solar cells. Due to the non-centrosymmetric crystal structure, third-generation semiconductor, such ZnO, AlN, GaN, InN, generate...
hedging is a multi-purpose rhetorical strategy which is usually used in scientific arguments to secure ratification of claims, reduce the risk of negation, avoid conflict, manage disagreement and leave room for the audience to assess presented information. hedges are frequently used in research articles to mitigate the findings of research endeavors. the present research aims to investigate the...
the current thesis is composed in five chapters in the following fashion: chapter two encompasses the applied framework of the project in details; the methodology of carl gustav jung to explain the process of individuation, the major archetypes and their attributes and his techniques to assess the mind’s strata are all explained. moreover, the austrian psychoanalysts, heinz kohut’s models of a...
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...
