Abstract

Silicon nanowires (SiNWs) were fabricated directly from the Si source gas into pre-fabricated permanent nanochannel templates by our self-assembling “grow-in-place” approach. The size, shape, position, orientation, and number of the SiNWs can be precisely controlled by the pre-fabricated nanochannel templates. Our approach is environmentally benign and friendly since only the exact number of SiNWs needed was grown and the SiNWs were always confined in the nanochannel templates. In addition, the templates can be fabricated with built-in contacts and integrated into the final devices, providing contacts, interconnects, and passivation/encapsulation. We are developing a variety of built-in ohmic and rectifying contact structures and approaches for the “grow-in-place” methodology. Some initial results will be discussed here.
