Single Electron Transport Through a Quantum Dot

Abstract

The push toward miniaturization has been a dominant technological force for the past 30 years. In addition to revolutionizing the computer world, this trend toward ever-smaller systems has profoundly influenced solid state physics. Using the fabrication technologies of the semiconductor industry, scientists can now routinely design electronic structures on a size scale where quantum effects are important. Their properties are regulated by quantization phenomena previously observable only in naturally occurring small systems. For example, current flow in these devices can be regulated by the fact that charge is quantized in units of e, just as quanta of charge regulated the falling of Millikan’s oil drops in 1909. Furthermore, electrons in these structures behave like the quantum-mechanical waves that Schrödinger, Bohr, and others used to describe the properties of atoms in the 1920s. The rapidly advancing fabrication techniques of the semiconductor industry have thus allowed physicists and engineers to make structures that probe the quantum properties of single electrons, but in novel and controlled geometries unavailable to previous generations of scientists.
