One-Dimensional Nanotemplate Structure of a Si(110) Substrate

Abstract

The process for the formation of a single-domain one-dimensional nanotemplate with a 16×2 reconstruction was investigated via scanning tunneling microscopy. Si(110) substrates with different resistivities were heated with direction-controlled direct currents. It was determined that obtaining a single-domain 16×2 reconstructed structure for a substrate with a lower resistivity even at the same annealing temperature is time consuming, which indicates that applied voltage rather than current flow plays a dominant role in single-domain formation.
