CBVB-nH complexes as prevalent defects in metal-organic vapor-phase epitaxy-grown hexagonal boron nitride

open access: yesnpj 2D Materials and Applications
Optically active defects in hexagonal boron nitride (hBN) are promising candidates for active components in emerging quantum technologies, such as single-photon emitters and spin centers.

The Photoionization Processes of Deep Trap Levels in n-GaN Films Grown by MOVPE Technique on Ammono-GaN Substrates

open access: yesApplied Sciences
In this paper, we present various theoretical models that accurately approximate the spectral density of the optical capture cross-section (σe0) obtained through the analysis of photo-capacitance transients using the deep-level optical spectroscopy (DLOS)

GROWTH OF GASB AND GAASSB IN THE SINGLE-PHASE REGION BY MOVPE

open access: yes, 1992
GaSb layers are grown on GaSb substrates; the effects of input partial pressure of trimethylantimony and the V/III ratio are studied. A model of the MOVPE phase diagram for the growth of GaSb and GaAsxSb1-x is developed which assumes thermodynamic ...

CALCULATION OF GROWTH RATES AND COMPOSITIONS OF NANOLAYERS InXGa1-XAs ON A InP SUBSTRATE USING A 3D MODEL OF A HORIZONTAL MOVPE REACTOR

open access: yesТонкие химические технологии, 2013
A three-dimensional (3D) detailed heat, mass and momentum transfer model was constructed to describe the thermal behavior, fluid dynamics and the diffusion in a horizontal metal-organic vapor-phase epitaxy (MOVPE) reactor with a rectangular section and a

Polarity of Hexagonal GaN Grown on GaAs (111)A and (111)B Surfaces by HVPE and Movpe

open access: yes, 2000
Summary:Dependence of hexagonal GaN polarity on the polarity of GaAs (111) substrates was investigated by CAICISS for HVPE and MOVPE. Although polarity of MOVPE GaN followed the polarity of GaAs substrate; Ga polar for (111)A and N polar for (111)B, both
