Band-gap shrinkage calculations and analytic model for strained bulk InGaAsP

InGaAsP photonic band gap crystal membrane microresonators*

We have microfabricated two-dimensional ~2D! photonic band gap structures in a thin slab of dielectric material to define reflectors and high-Q microresonators. By selectively omitting holes from the 2D photonic crystal, optical microcavities, and in-plane microresonator switches can be defined. We have designed this structure with a finite difference time domain approach, and demonstrate the e...

Equilibrium calculations for VPE-InGaAsP

2014 The heterogeneous equilibrium in the InGaAsP/HCl/H2 system has been studied at pressure and temperature conditions pertaining to the hydride-VPE growth. The results have been compared with the available experimental data on the growth of the above quaternary alloys lattice-matched to InP. A remarkably good agreement has been achieved with some existing data. Possible causes of discrepancie...

Towards efficient band structure and effective mass calculations for III-V direct band-gap semiconductors

The band structures and effective masses of III-V semiconductors InP, InAs, InSb, GaAs, and GaSb are calculated using the GW method, the Heyd, Scuseria, and Ernzerhof hybrid functional, and modified BeckeJohnson combined with the local-density approximation MBJLDA —a local potential optimized for the description of the fundamental band gaps F.
