Measurements of resonant tunneling through a localized impurity state are used to probe fluctuations in the local density of states of heavily doped GaAs. The measured differential conductance is analyzed in terms of ...

In order to find criteria for discrimination between surface color centers at terraces and steps, and bulk color centers, the characteristic losses of these centers have been investigated by electron energy loss spectroscopy ...

This paper examines in-depth processes of librarian professional identity negotiations impacting practitioners’ perception of, affiliation with, and behaviour within the profession. It outlines three key themes which ...
