Graphite free electrons

WebSep 12, 2024 · As given by Compton, the explanation of the Compton shift is that in the target material, graphite, valence electrons are loosely bound in the atoms and behave like free electrons. Compton assumed that the incident X-ray radiation is a stream of photons. An incoming photon in this stream collides with a valence electron in the graphite target. WebAug 17, 2024 · Stimuli responsive membranes, which are able to respond to environmental stimuli, are attracting ever-increasing interests.
