Far-infrared spectroscopy of the zinc acceptor in indium phosphide

摘要: We report the absorption spectrum of Zn acceptor in InP. Fourier interferometers equipped with Si bolometers were used to collect spectra at sample temperatures down 1.9 K. Zeeman measurements made Voigt configuration fields up 6.5 T electric field radiation, E, polarised either parallel or perpendicular magnetic field, Bjjh001i. Energies for G and D lines, corresponding transitions from 1s3=2 ðG þ Þ 2p3=2 � 2p5=2 states, respectively, are 241.5 0.2 286.0 cm 1 , respectively. Data taken higher resolution (0.05 ) indicate an intrinsic line width 0.5 full-width half-maximum a carrier concentration 4 10 16 3 . At low (B53 T), rapidly broadens, losing intensity becoming unresolvable. highest fields, four components EjjB two E?B resolved line.
