Growth of strained Ga_1-xIn_xP layers on GaP (001) by gas source molecular beam epitaxy: similarities and differences with the growth of strained arsenides

X. Wallart, D. Deresmes, F. Mollot

Using reflection high energy electron diffraction and atomic force microscopy, the growth of Ga1−xInxP alloys on GaP (0 0 1) with x varying from 0.2 to 1 (InP) is investigated and compared to that of arsenides on GaAs (0 0 1) or InP (0 0 1). At 520°C, the evolution of the critical thickness for 3D…

Detection of picosecond electrical pulses using the intrinsic Franz-Keldysh effect

Jean-Francois Lampin, L. Desplanque, F. Mollot

We report time-resolved measurements of ultrafast electrical pulses propagating on a coplanar transmission line using the intrinsic Franz-Keldysh effect. A low-temperature-grown GaAs layer deposited on a GaAs substrate allows generation and also detection of ps pulses via electroabsorption sampling…
