The electric-field effect on the exciton photoconductivity and Urbach tail in GaSe crystals

The direct free exciton (n = 1) photoconductivity in GaSe crystals has been investigated as a function of applied electric field. The changes observed in the exciton photoconductivity have been analyzed using the Franz–Keldysh, exciton electroabsorption, and Frenkel thermoelectric‐field effects. The...
