Research Abstract

Using the high precision ultrasonic mass flow controller, the strain-compensated superlattice was grown up to 90-pair (using previous controller 12-pair was a limit.) . Then, the originally planned technique, i.e., the adhesion process onto a transparent substrate, was not necessary and the adhesion process was not tried. In addition to it, lattice-matching and transparent substrate, ZnSe, was available and the growth of GaAs on ZnSe was successfully conducted. This also shows that the adhesion process was not necessary. Due to the stability of the appropriate excitation energy, use of semiconductor laser became possible. The excitation wavelength at the peak polarization located at the flat region (770~780nm) of the density-of states and then the quantum efficiency increased by 4 times.
