Modeling of High Temperature GaN Quantum Dot Infrared Photodetectors
In this paper, we present calculations for different parameters of quantum dot infrared photodetectors. We considered a structure which includes quantum dots with large conduction-band-offset materials (GaN/AlGaN). Single band effective mass approximation has been applied in order to calculate the electronic structure. Throughout the modeling, we tried to consider the limiting factors which dec...
متن کاملLarge Vacuum Rabi Splitting in a Single Nitride-Based Quantum WellMicrocavity
Here, we report a theoretical detailed study of Vacuum Rabi Splitting (VRS) in the system of Nitride Single Quantum Well (SQW) within a semiconductor microcavity. Distributed Bragg Reflectors (DBRs) containing ZnTe/ZnSe multilayers including GaAs microcavity and ( SQW at the center of microcavity, has been considered. Upper and lower exciton-polariton branches obtaine...
متن کاملLow-loss silicon nitride waveguide hybridly integrated with colloidal quantum dots.
Silicon nitride waveguides with a monolayer of colloidal quantum dots embedded inside were fabricated using a low-temperature deposition process and an optimized dry etching step for the composite layers. We experimentally demonstrated the luminescence of the embedded quantum dots is preserved and the loss of these hybrid waveguide wires is as low as 2.69dB/cm at 900nm wavelength. This hybrid i...
متن کاملMechanisms of postsynthesis doping of boron nitride nanostructures with carbon from first-principles simulations.
Electron-beam-mediated postsynthesis doping of boron-nitride nanostructures with carbon atoms [Nature (London) 464, 571 (2010); J. Am. Chem. Soc. 132, 13 692 (2010)] was recently demonstrated, thus opening a new way to control the electronic properties of these systems. Using density-functional theory static and dynamic calculations, we show that the substitution process is governed not only by...
متن کاملConductance in quantum wires by three quantum dots arrays
A noninteracting quantum-dot arrays side coupled to a quantum wire is studied. Transport through the quantum wire is investigated by using a noninteracting Anderson tunneling Hamiltonian. The conductance at zero temperature develops an oscillating band with resonances and antiresonances due to constructive and destructive interference in the ballistic channel, respectively. Moreover, we have fo...
