Vertical transport in type-II Heterojunctions with InAs/GaSb/AlSb composite quantum wells in a high magnetic field

electrons and two-dimensional QW electrons under quantum limit conditions for bulk electrons (B > 5 T). The electron concentrations in the substrate and InAs QW substrate into the InAs QW through the 2D electron states of ...

Luminescence red shift of InGaN/GaN heterostructures by enlargement of V-pits

quantum wells (QWs) from 10 to 60 were prepared to achieve a thick active MQW layer. The increasing QWs number leads to accumulation of strain in InGaN/GaN layers and opening’ semipolar QWs and c-plane QWs is incr...

Strong suppression of In desorption from InGaN QW by improved technology of upper InGaN/GaN QW interface

This work concentrates on the technology procedure for growth of upper QW interfaces in InGaN/GaN QW structure when different temperature for QW and barrier after QW formation was not interrupted, but immediately c...

LED-like structures with high temperature superlinear luminescence

The superlinear electroluminescence (SLEL) of the structures based on AlSb/InAsSb/AlSb deep quantum wells (QWs) grown by MOVPE on n-GaSb:Te substrates is presented. Two different Sb compositions were grown. Dependence QW we...

Influence of Different InGaN/(In)GaN Growth Modes on Indium Incorporation and Quality of Layers

In our work we will show how to significantly increase the In content in QWs without lowering the QW growth temperature. We have studied different growth modes of InGaN/(In)GaN heterostructure while the QW growth parameters...

Photoluminescence of InGaN/GaN MQW structures – technological aspects

of scintillator structures with different number of QWs and different growth rate of QWs were measured. We show that the growth rate and QW number are very important parameters to increase the QW excitonic lumines...

Advancement toward ultra- thick and bright InGaN/ GaN structures with a high number of QWs

well (QW) numbers ranging from 10 to 60 are described and discussed. It is shown that with increased QW number, the luminescence efficiency of the whole structure increases due to be in the range from 200 to 300 nm, which is obtain...
