Metallic point contacts formed by physical vapor deposition and chemical vapor deposition: microscopy study and point-contact spectroscopy
We have made an electron-microscopy study of nanoholes in membranes in successive stages of metal deposition using two different techniques: physical vapor deposition (PVD) and chemical vapor deposition (CVD). One-sided PVD (thermal evaporation) of gold and silver was used, as is relevant for hetero...
