Abstract

Recently, an anomalously large redshift of the absorption edge with electric field was claimed for β-GaSe1−x S x layered crystals. We have studied Bridgman grown ε-GaSe crystals as well as vapor transport grown β-GaS, and 2H-WSe2. While we have observed a shift in the absorption edge for ε-GaSe similar to that reported in previous work, our results demonstrate that the redshift arises from Joule heating, and is thus temperature induced, rather than intrinsic. For β-GaS, much larger resistivities virtually eliminate Joule heating, and our measurements of the electric field induced absorption edge shift yield an estimated upper limit of approximately 0.04 meV · cm/kV for a field of 2.4×103 kV/cm, in good agreement with the theoretical value expected for the Franz-Keldysh effect.
