While it is common knowledge that absorption of photons in the bulk of a semiconductor excites electrons from the VB to the CB, this work shows that a colliding atom may efficiently promote electrons in a similar way in a purely surface-specific process. The probability to convert translational...

Namely, holes preferably localize near two-fold coordinated N or five-fold coordinated Si, while electrons localize near three-fold coordinated Si or four-fold coordinated N. The trapping sites are statistically investigated by analyzing defect states in the band gap after capturing a charge and ...
In this case, HHG occurs in the regime of tunneling ionization of the atom and is the result of a three-step process, including the release of an active electron, its acceleration in the laser field, and subsequent recombination with the parent ion [14,15]. However, in recent years, the...

73 An atom that gains electrons becomes a ___ ion. 74 The goldfish has a round ___ (身体). 75 The ___ is the energy source for plants. 76 What do we call a baby chicken? A. Duckling B. Chick C. Gosling D. Piglet 77 The ___ (The Age of Enlightenment) influenced revolutions...
The first is to use Fischer-Tropsch synthesis, a process that catalytically converts SYNGAS to hydrocarbons of varying molecular weights. The second is methanol synthesis. The latter has better atomic economy, since the oxygen atom in CO is included in the product and CO2 can be blend...
effective nuclear charge- net charge an electron experiences in an atom that has multiple electrons. effervescence- foaming or bubbling when gas is evolved by a liquid or solid. efflorescence- process by which a hydrate loses water of hydration. ...

Since the s shell can hold only two electrons, the atom would be most stable by either gaining another electron or losing the existing one. Gaining an electron by sharing occurs in H2, where each H atom gains an electron from the other resulting in a pair of electrons being shared. The ...
