Temperature Dependence of Optical Absorption inp-Type Indium Arsenide

Evolution of Superluminescence Spectra of Indium Arsenide under Intense Photoexcitation

“…The results obtained enable us to make some additional conclusion concerning the energy structure of the valence band of indium arsenide. Basically, the energetic distance between the tops of the light-hole and heavy-hole bands in indium arsenide is rather close to the upper limit suggested by Matossi and Stern [7], i.e. 6 meV.…”

“…Here m lh is the effective mass of a light hole, m hh is the effective mass of a heavy hole. Neglecting nonparabolicity of the light-hole band by substituting m lh = 0.025m 0 and m hh = 0.4m 0 [6,7] we obtain the ratio of densities Dp lh /Dp hh % 1.5 Â 10 ± ±2 . The light holes can play, yet, a significant role by creating spontaneous as well as stimulated emission spectra in spite of their low density.…”

“…The valence band of indium arsenide is identical with the valence band of indium antimonide. The valence band maximum occurs at a wave vector of 0.0081 reciprocal Bohr radius, in the h111i directions and is supposedly 2.5 to 6 meV above the energy at k = 0 [7]. Some years ago we have observed superluminescence of indium arsenide under intense laser excitation [8].…”

Mobility of holes of zinc-blende III–V and II–VI compounds

“…[65] did not find any anisotropy of m, in his experiment. b) The experimental value of the reflectivity mass was found t o be strongly 0 ) This value is the density-of-states mass as calculated in[69].d) Calculated assuming m, = 0.027 m,,. e) References are given in [55].…”

Innere Bandübergänge als Absorptionsmechanismus freier Ladungsträger in Halbleitern (II)

“…So gelang z. B. MATOSSI und STERN[67] eine derartige Analyse anhand der Temperaturabhdngigkeit der p-Bande in InAs (vgl. weiter unten).Ferner 1aBt sich, wie bei Germanium, bei bestimmten Verbindungshalbleitern aus dem genauen spektralen Verlauf der Absorptionsbanden der Intrabandubergange eine Abweichung des Bandverlaufs von der Parabolizitat bei wachsenden f-Werten ermitteln.…”
