Abstract: Methods of in situ fabrication and formation of horizontal nanowires for a semiconductor device employ non-catalytic selective area epitaxial growth to selectively grow a semiconductor material in a selective area opening of predefined asymmetrical geometry. The selective area opening is defined in a dielectric layer to expose a semiconductor layer underlying the dielectric layer.

The semiconductor material is further selectively grown to fill the linear nanogap template to in situ form the nanowire that is uniformly linear.
