High Pressure Study

ABSTRACTWe report on a high pressure study of emission from a series of GaInP(ordered)/GaAs heterostructures. A so-called “deep emission” band at 1.46 eV is observed in all our samples. At high excitation power, quantum well emission emerges in only one structure where thin GaP layers are inserted on both sides of the GaAs well. From the pressure dependent emission in this sample we have determined its band alignments. The role of the GaP layers in suppressing the deep emission is elucidated.

Homogeneous Reaction

The pyrolysis of hexafluoroazomethane has been studied in a static system between 0.3 mm and 73 mm and 572 °K and 634 °K by measuring the rate of nitrogen formation. The rate constant of the high-pressure homogeneous reaction is given by k = 1016.17±0.15 exp (−55,200 ± 400/RT) sec−1
