We have investigated the doping of the top and the top few layers of graphite with nitrogen,and atomic oxygen using scanning tunneling microscopy(STM)in ult
In this work,we achieve the layer-by-layer epitaxial growth of LaCoO3 thin films on polar SrTiO3(111)substrate by pulse laser deposition(PLD)assisted by ref
Searching for new superconducting film materials and studying their superconductivity have become the frontier scientific research areas in condensed matter
