Defect incorporation in In-containing layers and quantum wells: experimental analysis via deep level profiling and optical spectroscopy

F. Piva et al.

Summary: Recent studies have shown that the performance of InGaN/GaN LEDs can be improved by inserting an InGaN underlayer. The underlayer helps reduce the density of non-radiative recombination centers in the quantum well, limiting the propagation of defects towards the QWs. Experimental data supports this hypothesis and provides insights into the properties of related traps.

n-type GaN surface etched green light-emitting diode to reduce non-radiative recombination centers

Dong-Pyo Han et al.

Summary: This study identifies the presence of surface defects at an n-type GaN surface following high-temperature growth, mainly attributed to nitrogen vacancies and related point defects. Surface etching of n-type GaN can enhance the photoluminescence efficiency of green LEDs by removing surface defects and reducing non-radiative recombination centers, thereby improving the LED performance.

GaN buffer growth temperature and efficiency of InGaN/GaN quantum wells: The critical role of nitrogen vacancies at the GaN surface

Yao Chen et al.

Summary: This study investigates the impact of GaN-buffer growth temperature on the efficiency of InGaN/GaN quantum wells, revealing that high-temperature growth promotes the creation of surface defects leading to a collapse in internal quantum efficiency. Theoretical analysis suggests that these defects are likely to be nitrogen vacancies. Furthermore, the study shows that surface defects are mainly generated at the early stage of GaN growth and reach a steady state concentration determined by the growth temperature.
