Abstract
In this paper, we have investigated the current-voltage (I-V) characte ristics of crystalline Si (c-Si)/porous Si/metal structures for differ ent substrate resistivities from 0.01 to 75 Omega cm. We find that the I-V characteristics for low-resistivity samples are nonlinear and pse udosymmetric. For samples with a substrate resistivity greater than 1 Omega cm, the I-V characteristics exhibit rectifying behaviour. The I- V characteristics of the latter samples are weakly dependent on temper ature. We present a model which invokes tunnelling to explain electron ic transport in this system.
