Title: The structure and fabrication method of infrared quantum dot light emitting diode
Inventor: TANG SHIANG-FENG
IPC: H01L33/06
Filed: 2003-03-19
Granted: 2005-07-01
Abstract: We have fabricated the InAs/GaAs quantum dot edge light emitting diode with the peak emission wavelength of 1 mum. The shift of peak wavelength is 0.22 nm/K under 20 to 300 K. The temperature-dependent broadening of of full width at half maximum (FWHM) of electro-luminescence (EL) spectrum is 0.04 nm/K. Strained layer epitaxy is an effective method to fabricate self-assembled zero dimensional (0D) InAs/GaAs quantum dots. The 7% lattice mismatch between the epitaxial InAs and GaAs is induced the Stransky-Krastanov growth mode. The device was grown by solid-source molecular beam epitaxy. We have displayed the temperature-dependent I-V characteristics and ideality factor of three period InAs/GaAs QD LED. From 20 to 300 K, the dark current is fall from 84 pA to 13 nA at the negative bias of -0.5 V. The ideality factor was 14 (tunneling current is dominant) at 20 K abruptly down to ~ 2 (G-R current) at the range of 100 to 240 K, then approaches to ~ 1.3 (diffusion current) smoothly. It reveals that the device has low dark current and excellent diode electric performance. The position of peak wavelength and FWHM of the EL spectrum were extracted and displayed. The position of peak wavelength is from 0.99 to 1.05 mum due to energy gap shrinkage of semiconductor when increasing temperature. Operated at the very large temperature range, the wavelength shift and the broadening FWHM are only 0.22 and 0.04 nm/K, respectively. These results are comparable with resonant cavity LED and the LED with the surfacing multiplayer dielectric optical filter. The intensity versus current (L-I) characteristics is essentially linear at the temperature range. The equivalent threshold currents are caused by the parallel constant current leakage path which are independent with temperature. The slopes of L-I decrease with the increasing of temperature. We have measured the I-V and EL as the function of temperature to demonstrate the excellent device performance and temperature-insensitivity.
