As device sizes shrink on chips, earlier assumptions made in modelling electron and hole transport are starting to break down. Ferry explores the many consequences of this. Now that we can use lithography and associated techniques to make devices less than 0.1 micron, quantum effects can arise.



These might include a two dimensional electron gas, where one spatial dimension is essentially suppressed by the heterostructure. Perhaps under the gate of an experimental transistor. Other contexts might be fluctuations in the atomic distribution seen by a transport electron or hole. This might importantly include fluctuations in how dopants are arranged. Leading to regions of differing conductance.



Ferry investigates these and other phenomena like quantum wires and dots, at a level well placed for the graduate student or researcher.
