Electrons are tiny and constantly in motion. How they behave in a crystal lattice determines key material properties: electrical conductivity, magnetism, or novel quantum effects. Anyone aiming to ...

Abstract: In this paper, we present a technique for local measurements of the surface potential in the presence of a biasing current flow through a sample. This technique can be implemented by using ...
