Abstract(in English) | The optical property of GaN nanocolumns grown on (0001) Al_2O_3 substrates was characterized by room temperature photolummescence (PL) measurement For the case of low excitation condition, the PL peak intensity of the GaN nanocolumns was about 20~400 times stronger than that of an undoped GaN continuous film grown by metalorganic chemical vapor deposition with a dislocation density of 3~5x10^9cm^<-2> and thickness of 37 μm For the higher excitation condition, stimulated emission was observed with a low threshold power density of 198 kW/cm^2 We also grown GaN nanocolumns with InGaN/GaN multiple quantum well. Bright PL emission at wavelength from 436 to 614 nm was observed InGaN/GaN multiple quantum well nanocolumn LEDs were grown on n-type (111) Si The LEDs showed clear rectifying behavior Green to red-orange electro-luminescence was obtained at room temperature |
