摘要：

GaSe and related layered crystals were grown by the Bridgman method. Thin samples were obtained by cleaving. Transmission spectra of the thin samples were measured under an electric field with both incident direction and field direction parallel to the c-axis. The absorption edge shifted forward longer wavelength by 20 nm under an electric field of as low as 1 kV/cm. The shift is more than two orders larger than evaluated on the Franz-Keldysh mechanism. © 1990 The Japan Society of Applied Physics.
