Abstract

In this paper, we have investigated GaN/AlGaN Modified Quantum
Dot (MQD) nanocrystal and GaN/AlGaN/GaN/AlGaN Quantum Dot-
Quantum Well (QDQW) heteronanocrystal which has been analyzed
by the Finite Element Numerical Methods (FEM). Simulations
carried out for state n=1, l=0, and m=0 which are original, orbital,
and magnetic state of quantum numbers. The effects of variation
of radius layers such as total radius, GaN core, shell, and AlGaN
barriers radius on the wavelength and emission coefficient are
studied. Furthermore, window of 330-410nm wavelength detected by
these structures, provides us facility to detect the light of UV solidstate
lasers that are in 349, 351, 355 and 375nm wave length. These
suggested structures can be used for medicine, telecommunications
and computing (optical storages).
