Quasi-coherence and the Field Effect in Ga(As, P) “Fractal” Superlattice for Functional Photonic Devices
نویسنده
چکیده
Quasi-coherence in the Ga(As,P) fractal lattice (FL) has been observed by tunneling photo current excitation (TPCE) and photo-reflectance (PR) measurements. These results are consistent with the quasi-subband formation in the FL calculated by transfer matrix method. We discussed the coherence breaking and deformation of the quasi-subband with applying electric field on the basis of results of transfer matrix calculation.

Design of low-dispersion fractal photonic crystal fiber
In this paper, a fractal photonic crystal fiber (F-PCF) based on the 1st iteration of Koch fractal configuration for optical communication systems is presented. Complex structure of fractal shape is build up through replication of a base shape. Nowadays, fractal shapes are used widely in antenna topics and its usage in PCF has not been investigated yet. The purpose of this research is to compar...
متن کاملFirst Principle Study of MC (M= Al, Ga, and In) at Equilibrium and under Negative Stress
The electronic and magnetic properties of the hypothetical compounds of MC (M=Al, Ga and In) are investigated by using first-principle calculations and pseudopotential plane wave self-consistent field method based on density functional theory. In order to find the most stable phase of MC (M=Al, Ga and In), we study them in zinc-blende (ZB), rocksalt (RS), wurtzite and NiAs crystal structures. W...
