Conversion of Photons to Electrons in a Single
... showed that the emission linewidth of both InP and InAsP is very broad. The broadening can be attributed to surface states in general and charging in the case of the quantum dot. Photocurrent measurements on intrinsic nanowires showed very fast photoresponse which is on the order of ms. Whereas n-ty ...

Fusion reactor concepts in which a particle is lost after being scattered would generate only a small amount of fusion reactions since most of the collisions would in fact be elastic. A successful concept, therefore, must allow for many ...

Time in physics
Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
