COHERENT ELECTRON TRANSPORT IN SYSTEMS OF QUANTUM DOTS

Tigran V. Shahbazyan

Jackson State University, Jackson, MS

In this talk, I will address coherent effects in resonant tunneling of an electron through systems of quantum dots (QD) sandwiched between modulation-doped semiconductor leads. The interference between different tunneling paths provided by a QD system can lead to striking features in tunneling current. Some of the coherent effects in electron transport can be best understood in optical terms, while some are useful in interpreting optical phenomena. I will discuss the Dicke effect in resonant tunneling through a pair of QDs independently connected to the leads, and electron transmission through periodic QD arrays.
