Two-dimensional (2D) transition-metal dichalcogenides have attracted significant attention as gas-sensing materials owing to their superior responsivity at room temperature and their possible application as flexible electronic devices. Especially, re

The effect of electron blocking layer (EBL) on the injection and radiative efficiencies in InGaN/GaN multiple quantum well (MQW) light-emitting diodes (LEDs) was investigated. In order to identify the dominant mechanism, we measured the external quan

We analyzed the current-crowding process and its effects on carrier spill-over and light outputpower loss in InGaN/GaN blue-light-emitting diodes. When the current density was measured to be 3.1 times larger, the carrier spill-over was observed to be

The carrier injection efficiency (CIE) and the radiative efficiency (RE) are experimentally determined in order to clarify the origin of the efficiency droop in blue-emitting GaN light emitting diodes. The difference in the shape of RE curves and the
