Link of the week - Salute to SALUTE

Abstract:
SALUTE—or Stochastic ALgorithms for Ultra-fast Transport in sEmiconductors—is a pilot grid application developed to solve computationally intensive problems in semiconductor physics.

Semiconductors—materials that can both conduct and insulate electricity—are invaluable to modern electronics. Their ability to conduct depends on the ability of "carriers"—electrons or phonons—to transport electrical charge.

This carrier transport occurs on a quantum level: the temporal scale is so short it is measured in femtoseconds, where one femtosecond is 10-15 seconds, or one millionth of a nanosecond.

Simulations on this sort of scale rely on complicated integral equations, solvable using SALUTE's novel and grid-enabled Monte Carlo algorithms.

Global impact

Studying the quantum effects that occur at the nanometer and femtosecond scale has important scientific and social impact, since they can improve the process of designing nano-devices.

Scientists and engineers working in nanotechnology, including those from Austria, Bulgaria, Croatia, the UK and the U.S., have already expressed interest in SALUTE results.
