Observation of Exciton Fine Structure in the Interband Magnetoabsorption of InSb and Germanium

Diamagnetic excitons and the indium antimonide energy band parameters

“…It may be suggested that the experimental technique employed by Weiler [3] produces stress in the crystal. We note that the value of the band gap, .sg = 0.2367 eV, close to the one used by us was obtained also by Johnson [12].…”

“…The dependence of the DE binding energy on magnetic field estimated experimentally from the difference -E , =~ agrees well with the theory of [5] including band nonparabolicity. It should be noted, however, that the nature of the short-wavelength satellite of the OMA main line observed' without any additional features by Johnson [12] cannot certainly be reduced to the v = 1 excited state only as this was suggested in [ E l , but includes rather the continuum states as well.…”

Exciton and polaron properties in GaxIn1−xAs ternary mixed crystals

“…Exciton effects have been observed in magneto-optical experiments [13] and the exciton binding energy can be estimated. Furthermore, in organic semiconductors and solar cells, the role of excitons is essential, as the primary effect of light absorption is exciton generation, and free electrons and holes are created by exciton dissociation [14].…”

Direct Exciton Spectrum in Diamond and Zinc-Blende Semiconductors

“…Since the first observation by Macfarlane et al 1 and Zwerdling, Roth, and Lax 2 of the direct exciton in Ge, many authors have investigated direct excitons in III-V 3 and II-VI 4 compounds. In substances where the exciton has a small binding energy and cannot be observed directly, effects due to exciton formation have been observed in magneto-optical experiments 5 and an estimate of the binding ener-gy is possible.…”
