GaSb/InAs heterojunctions grown by MOVPE
Abstract We have previously reported the MOVPE growth of a GaSb/InAs heterojunction containing a two-dimensional electron gas (2DEG) in the InAs [1]. A major improvement in the electrical quality of InAs layers has subsequently resulted from the use of tertiarybutylarsine (TBAs) as the arsenic source.

The microstructural and morphological properties of homoepitaxial (001)ZnTe layers are investigated by x-ray diffuse scattering. High resolution reciprocal space maps recorded close to the ZnTe (004) Bragg peak show different diffuse scattering features.

Effect of multilayer barriers on the optical properties of GaInNAs single quantum-well structures grown by metalorganic vapor phase epitaxy [PDF]
We report on the effects of combined strain-compensating and strain-mediating layers of various widths on the optical properties of 1.3 μm GaInNAs∕GaAs single quantum well structures grown by metalorganic vapor phase epitaxy (MOVPE).

Detailed models of the MOVPE process
Abstract We present physicochemical models of the MOVPE process that describe two- and three-dimensional transport phenomena as well as gas-phase and surface reactions underlying the growth of compound semiconductors. Emphasis is placed on understanding the development of fully three-dimensional flows and on the interaction between transport and ...

A heterogeneous III‐V/SiN platform for lasers at 800 nm is realized using the micro‐transfer printing method. Efficient GaAs gain sections are directly butt‐coupled to SiN waveguides, enabling continuous‐wave and mode‐locked extended‐cavity lasers. The mode‐locked lasers generate highly stable pulse trains with repetition rates up to 9.2 GHz and a ...

Growth parameters of InAs/GaAs quantum dots grown by MOVPE [PDF]
Quantum dots are zero dimensional structures and therefore have superior transport and optical properties compared to either 2-dimensional or 3-dimensional structures.

Illumination and annealing characteristics of two-dimensional electron gas systems in metal-organic vapor-phase epitaxy grown AlGaN/AlN/GaN heterostructures [PDF]
We studied the persistent photoconductivity (PPC) effect in AlGaN/AlN/GaN heterostructures with two different Al-compositions (x=0.15 and x=0.25). The two-dimensional electron gas formed at the AlN/GaN heterointerface was characterized by Shubnikov-de ...

Impact of Polarization Charges on Threshold Voltage and Band Offset in AlGaN/GaN Heterostructures
The threshold voltage for the two‐dimensional electron gas of GaN‐based heterostructures is analyzed by considering the thickness of the polarization charge region at a semiconductor surface and interface. The proposed model gives the threshold voltage agreed with experimental results.
