EL and PL of uncoated sample with arm-arm injection scheme By Shu-man Liu

Sample: 8_4_05.2#2E 1.Sample structure and composition 2.MicroPL scanning along to the wire 3.MicroPL with forward bias below the EL threshold 4.EL measured at 大部屋の奥 5.EL measured at 大部屋の右 6.Lasing under optical pumping with and without forward bias 7.PLE

Structure

MicroPL scan along the wire Standby

PL under various bias PL decreases suddenly and then increases with bias voltage.

EL measured at 大部屋の奥 On-axis Emissive position changed

EL measured at 大部屋の右 (2K-80K)

Lasing by optical pumping with and without forward bias Standby Bias=1.5V

Supplementary Experiments in the near future EL and PL images Polarization dependent PLE Absorption by Hakki-Paoli method
