Publikováno v: 2017 22nd Microoptics Conference (MOC).

We investigated the gas flow sequence to realize short period and lattice matched InAs/GaAsSb superlattice on InAs substrate by MOVPE. Arsenic composition of GaAsSb for lattice matching was adjusted by adding AsH 3 flow to residual arsenic incorporat

Constrained self-consistent field method revisited toward theoretical designs of functional materials under external field

Autor: Hiromi Nakai, Yuya Yamagata, Yutaka Imamura

Publikováno v: Chemical Physics Letters. 530:132-136

This Letter explores the potential utility of the constrained self-consistent field (CSCF) method as an efficient methodology for estimating the external fields that reproduce desired physical quantities. Using the fact that a Lagrange multiplier int

We investigated the gas flow sequence to realize a short-period and lattice-matched InAs/GaAsSb superlattice on an InAs substrate by metalorganic vapor phase epitaxy (MOVPE) growth for applications in mid-infrared photonic devices. The arsenic compos
