ScholarBank@NUS Repository.||Abstract:||Scanning tunnelling microscope (STM) modifications on α-WO3-x thin films were carried out in air. Holes and bumps were produced. Two mechanisms were clarified with respect to the water layer attached more or less in modifications. By applying voltage pulses, the high humidity (>60%) raised the probability of hole formations. Connection lines were formed between the holes, confirming a dominant electrochemical nature. The low humidity (||Source Title:||Japanese Journal of Applied Physics, Part 1: Regular Papers and Short Notes and Review Papers||URI:||http://scholarbank.nus.edu.sg/handle/10635/82743||ISSN:||00214922|
