Modeling of Quantum Transport in Semiconductor Devices (The Physics and Operation of Ultra-Submicron Length Semiconductor Devices).
Abstract
The evolutionary decrease in the size of an individual semiconductor device continues with no apparent end of the process in sight. As a consequence, it is quite likely that critical dimensions will soon be comparable to quantum coherence lengths for the particles 'Involved in the transport within the device. Generally, quantum transport differs from semi-classical transport in the utilization of a quantum kinetic equation (as opposed to the Boltzmann transport equation). These quantum kinetic equations can be developed for the density matrix, the Wigner distribution function, and real-time Green's functions, as well as for many reduced approximations to these quantities. In this review, we study how these various approaches are connected as well as how they offer different views into the quantum behavior within devices.
