摘要：
Electrical properties of stoichiometry-controlled single crystals of CuInSe2 are investigated by the Hall effect measurement over the temperature range of 20 to 300 K. Overshoot characteristics have been observed in the temperature dependence of the Hall coefficient for all p-type crystals. The compensating donor density is shown to be a dominant factor for the Hall overshoot rather than the acceptor density. If we assume a relation that mu(n)/mu(p) = Const. T(-eta) with eta around 1.5, the Hall overshoot is well explained.
