Silicon Metal-oxide-semiconductor Quantum Dots for Single-electron Pumping
As mass-produced silicon transistors have reached the nano-scale, their behavior and performances are increasingly affected, and often deteriorated, by quantum mechanical effects such as tunneling through single dopants, scattering via interface defects, and discrete trap charge states. However, progress in silicon technology has shown that these phenomena can be harnessed and exploited for a n...
متن کاملEffect of light Polarization on the absorption index of alkali metal vapor in optical pumping phenomenon
Recently atomic magnetometers are one of the best tools in biomagnetic measurement such as magnetic field of brain and heart. In this paper, the technology of optically pumped atomic magnetometer based on circularly polarized light absorption pumping is described. We have been investigated a new method for measuring polarization effect in an alkali vapor based on polarized light transmission. I...

متن کاملOptical Pumping
T he rather odd term optical pumping means just what it says. In general “pumping” is a process of raising matter from lower to higher energy; for example, raising the potential energy of water hy moving it from an underground well to an elevated tank. In this article we shall he concerned w i t h the pumping of individual atoms from lower to higher states of internal energy. The word optical r...
متن کاملOptical Pumping
Optical pumping uses light to affect the internal degrees of freedom of a sample of atoms in a vapor. These internal degrees of freedom are angular momentum states of the atomic ground state, which are populated when light is absorbed and emitted. This experiment reveals many phenomena of quantum mechanics including angular momentum selection rules, the density matrix, and resonance. Optical pu...
