We present a simulation based investigation of the dependence of the device characteristics on the quantum well width in AlGaAs/GaAs quantum well infrared photodetectors (QWIPs) through the ensemble Monte Carlo technique. The simulations on two different standard Al0.3Ga0.7As/GaAs QWIPs with quantum well widths of 36 and 44 Å have shown that the gain in the former is considerably higher, which is due to much longer lifetime of the photoexcited electrons as a result of lower capture probability in the device. We discuss this observation by the investigation of the electron scattering rates in these structures through realistically evaluated scattering mechanisms between two and three-dimensional states in the multi-quantum well structure

Diffraction-Grating-Free Very Small-Pitch High-x InP/InxGa1-xas Quantum Well Infrared Photodetectors Beşikci, Cengiz; Balci, S.V. (2022-08-01) We report diffraction-grating-free mid-wavelength infrared quantum well infrared photodetector pixels with small pitches (down to an area of 49 μm2) which exhibited remarkable peak conversion efficiency (70%) together with f/2 peak specific detectivity of ∼ 1.5×1011 cmHz1/2/W at 78 K. The sensors were fabricated with In0.85Ga0.15As quantum wells sandwiched between InP barriers. The pixels with 22% peak quantum efficiency exhibited background limited characteristics at 90 K with f/2 aperture and ∼ 6μm cut-of...
Quantum Monte Carlo methods for fermionic systems : beyond the fixed-node approximation Dugan, Nazım; Erkoç, Şakir; Department of Physics (2010) Developments are made on the quantum Monte Carlo methods towards increasing the precision and the stability of the non fixed-node projector calculations of fermions. In the first part of the developments, the wavefunction correction scheme, which was developed to increase the precision of the di usion Monte Carlo (DMC) method, is applied to non fixed-node DMC to increase the precision of such fermion calculations which do not have nodal error. The benchmark calculations indicate a significant decrease of st...
Nonlinear optical properties of semiconductor heterostructures Yıldırım, Hasan; Tomak, Mehmet; Department of Physics (2006) The nonlinear optical properties of semiconductor heterostructures, such as GaAsAl/GaAs alloys, are studied with analytic and numerical methods on the basis of quantum mechanics. Particularly, second and third-order nonlinear optical properties of quantum wells described by the various types of confining potentials are considered within the density matrix formalism. We consider a Pöschl-Teller type potential which has been rarely considered in this area. It has a tunable asymmetry parameter, making it a goo...
A coordinate transformation approach for efficient repeated solution of Helmholtz equation pertaining to obstacle scattering by shape deformations Ozgun, Ozlem; Kuzuoğlu, Mustafa (2014-06-01) A computational model is developed for efficient solutions of electromagnetic scattering from obstacles having random surface deformations or irregularities (such as roughness or randomly-positioned bump on the surface), by combining the Monte Carlo method with the principles of transformation electromagnetics in the context of finite element method. In conventional implementation of the Monte Carlo technique in such problems, a set of random rough surfaces is defined from a given probability distribution; ...
High performance focal plane array technologies from short to long wavelength infrared bands Arslan, Yetkin; Beşikci, Cengiz; Department of Electrical and Electronics Engineering (2014) This thesis work covers the development of three different state of the art infrared sensor technologies: quantum well infrared photodetectors (QWIPs), HgCdTe sensors and extended InGaAs photodetectors. QWIP is the leading member of the quantum structure infrared photodetector family providing excellent uniformity and stability with field proven performance. The utilization of the InP/In0.48Ga0.52As multi-quantum well structure (instead of the standard AlGaAs/GaAs material system) for the implementation of ...
