A New Model for the Absorption Coefficient of Narrow-Gap (Hg,Cd)Te That Simultaneously Considers Band Tails and Band Filling. (9999)

Herrmann, K. H., Happ, M., Kissel, H., Moellmann, K. P., Tomm, J. W.

A semiempirical model is presented that correlates the broadening of the absorption edge with both transitions below the energy gap and with transitions by the Kane band model. This model correctly...

Photoluminescence and photoluminescence excitation studies of lateral size effects in Zn_{1-x}Mn_xSe/ZnSe quantum disc samples of different radii (1998)

Klar, P. J., Wolverson, D., Davies, J. J., Heimbrodt, W., Happ, M., Henning, Torsten

Quantum disc structures (with diameters of 200 nm and 100 nm) were prepared from a Zn_{0.72}Mn_{0.28}Se/ZnSe single quantum well structure by electron beam lithography followed by an etching...

Evidence of Hybridization from a direct comparison of semimagnetic and nonsemimagnetic ternary lead chalcogenides (1994)

Herrmann, K.H., Happ, M., Möllmann, K.-P., Peuker, F., Tomm, J.W., Böttner, H., ...

The results of a study of the optical properties, especially the luminescence behaviour, of PbSe, Pb1-xSrxSe and semimagnetic Pb1-xEuxSe in magnetic fields up to 7 T are presented. The spectra of...
