We examine the possibility of excitonic superconductivity at a metal-semiconductor interface. An ab initio RPA calculation of the screened Coulomb electron...
Although experimentation is an accepted approach toward scientific validation in most scientific disciplines, it only recently has gained acceptance within the...
A precast, prestressed concrete framing system for resisting earthquake loads is described. The system uses both unbonded post-tensioned reinforcement and...
Although the statistical thermodynamics of noncovalent binding has been considered in a number of theoretical papers, few methods of computing binding...
Using a 10.5 GHz resonant electro-optic modulator placed inside a resonant optical cavity, we have generated an optical frequency comb with a span wider than 3...
The desorbed fluxes of gallium atoms from a GaAs (100) substrate during GaAs growth in the temperature range 550 to 1015 K are directly measured with laser...
Ion traps allow researchers to control the position and movement of charged particles with exquisite precision, and provide a powerful way to study many atomic...
