introduction to nanoscience

... level of detail varies from topic to topic, mostly reflecting our tastes and experiences rather than the importance of the topic. We provide a significant number of references to current research literature: ... QPC. To illustrate this, let us concentrate on the energy E that lies close to the top of the barrier W n at certain n y , E = W n + δ E, |δ E|W n . In this case, the potential...
