thermal evaporation metal evaporation MET metal shadowing metal evaporation technique A synthesis technique where the substrate is placed in a vacuum (<10^{-4} Pa) and a metal electrode (e.g. Au, Cr, Zn or Pt) is melted and evaporated by passing a current through it. When the metal atoms hit the (μch cooler) substrate they condense into nanoscale particles, forming a thin deposit on the surface. CHMO:0001361 ME metallisation
