The seminal recent discovery of a two-dimensional electron gas (2DEG) ... allowing the total surface charge density to be determined as 7.1±2×10 13 cm −2.

Surface charges play an important role in the catalytic reaction in photoelectrochemistry. However, the spatial heterogeneities of charge transfer sites and catalytic sites at the electrode ...

This, in turn, results in a standing-wave-like periodic distortion in the otherwise uniform charge (electron) density, and hence the name charge density wave. R.E. Peierls showed in 1930 that for a ...
