Hybrid detector based on MOVPE grown InGaN/GaN MQW + BGO

InGaN/GaN MQW structures for scintillators grown by MOVPE were prepared, measured and optimized. Exciton and defect PL bands, as well as PL kinetics, were measured. Design and construction of a hybrid InGaN/GaN...

A hybrid detector based on MOVPE-grown InGaN/GaN multiple quantum wells with BGO scintillator layers

particles. MOVPE InGaN/GaN MQW scintillation structures were prepared and studied. The highest distance of two adjacent QWs ought to be lower than diffusion length of GaN exciton. We have realized alternative solu...

MOVPE growth of InGaN/GaN MQW nitride scintillator structure

morphological problem of the InGaN/GaN MQWs is formation of V-pits. These V-pits originate in InGaN QWs and they are created due to dislocations. InGaN/GaN structures with a different number of QWs and di...

InGaN/GaN multiple quantum well structures for scintillator application

Scintillator InGaN/GaN QW structure was prepared by MOVPE. The structure reported is a promising candidate for fast scintillator applications: the scintillation response characteristics are better compared to the currently ...
