Optical properties of photodetectors based on wurtzite quantum dot arrays

Polarization-resolved fine-structure splitting of zero-dimensional InxGa1−xN excitons

“…9), corresponding to a threefold proper rotation axis [0001] (c axis) contained in three vertical reflection planes. The exciton states and the corresponding optically allowed transitions for C 3v -symmetry QDs were reported in Ref.…”

Development of adaptive filtering for nanosatellite electron-optical device based on the «Synergy» platform for researching the North-West region of Russia

“…The multiplicative component includes dynamically changing noise. Figure 2 shows a diagram showing the causes of various noises [3][4][5][6][7][8][9].…”

“…The main reason for the occurrence of dark current is thermionic emission, which depends on the temperature level of the CCD matrix crystal. The noise arising from the dark current also depends on the exposure time, and the dependence is directly proportional [3][4][5][6][7]. This noise is a random process and can be described using a Poisson distribution.…”

Excitonic and biexcitonic properties of single GaN quantum dots modeled by 8-bandk⋅ptheory and configuration-interaction method

“…Although it has relatively small values in III-nitrides ͑ϳ10-20 meV͒ when compared to the fundamental energy gap at the ⌫ point ͑Ͼ2 eV͒, the spin-orbit interaction splits the fourfolddegenerate top valence band ͑⌫ 6 symmetry͒ into two twofold-degenerate bands ͑⌫ 9 and ⌫ 7 ͒. 35,36 Consequently this simplification leads to block diagonalization of the Hamiltonian into two identical 4-band Hamiltonians. For the present work we choose the more sophisticated 8-band Hamiltonian.…”
