Temperature dependence of the average electron-hole pair creation energy in Al0.8Ga0.2As

MEASUREMENTS OF THE AVERAGE ENERGY PER ELECTRON-HOLE PAIR GENERATION IN SILICON BETWprEEN 5-32O0K(

The average energy exDended to create an electron-hole pair in silicon ESi(T) has been measured in the 5-3200K temperature range with thin totally depleted surface barrier and diffused junction radiation detectors. The data have been normalized to a value of ESi (3000K) = 3.62 eV. A dependence of ESi on T much weaker than previously published by other authors has been observed. In the examined ...

Electron hole pair mediated vibrational excitation in CO scattering from Au(111): incidence energy and surface temperature dependence.

We investigated the translational incidence energy (Ei) and surface temperature (Ts) dependence of CO vibrational excitation upon scattering from a clean Au(111) surface. We report absolute v = 0 → 1 excitation probabilities for Ei between 0.16 and 0.84 eV and Ts between 473 and 973 K. This is now only the second collision system where such comprehensive measurements are available - the first i...

General Theory of Cycle-Dependence of Total pi-Electron Energy

The theoretical treatment of cycle-effects on total pi-electron energy, mainly elaborated by Nenad Trinajstic and his research group, is re-stated in a general and more formal manner. It enables to envisage several other possible ways of measuring the cycle-effects and points at further directions of research.

Experimental Determination of Electron-Hole Pair Creation Energy in 4H-SiC Epitaxial Layer: An Absolute Calibration Approach

Wormholes and Black Hole Pair Creation

We analyze the possibility of black holes pair creation induced by three dimensional wormholes. Although this spacetime configuration is nowadays hard to suppose, it can be very important in the early universe, when the wormhole spacetime foam representation can be meaningful. We compare our approach with the no-boundary prescription of Hartle-Hawking. PACS numbers: 04.60, 04.70.Dy, 98.80Hw Typ...
