He recently worked out a relatively inexpensive and easy way to etch metals using some chemistry skill and a little bit of electricity. After preparing a set of stencils and cleaning the metal ...

Curiosity about a mistake that left tiny dots on a germanium wafer with evaporated metal films led to the discovery of beautiful spiral patterns etched on the surface of the semiconductor by a ...

These fluorination and ligand-exchange reactions lead to atomic layer controlled etching. This ALE approach is extendible to other materials besides metal oxides. Our current work has demonstrated the ...
