Tunneling through a tilted tight-binding band.
In the single-band approximation, an explicit expression of the exponential factor, that governs tunneling through a thin crystal subjected to a constant electric field, is derived. The basic features of Wannier-Stark, Airy, and intermediate type of quantization, as they are displayed in the transmission spectrum and hence in tunneling current, are thus described analytically.
