Analog passive

Besides the electrically active complexes discussed above, there is indirect evidence for the existence of neutral complexes. In close analogy to the observations in silicon and several III-V materials it appears that hydrogen passivates deep and shallow acceptors. Because of the small concentrations of these neutral centers, all attempts to detect them directly with local vibrational mode (LVM) spectroscopy or electron paramagnetic resonance (EPR) have been unsuccessful. [Pg.368]

We proceed now to discuss the analogous hydrogen-related complexes with shallow-level impurities. We will find that the way hydrogen incorporates itself and the character of the complex after it is formed is independent of whether the passivated impurity introduced a deep level or a shallow level. Therefore, many of the basic arguments regarding the complexes will prevail as we consider the shallow-level defects. [Pg.541]

In addition to the universal concern for catalytic selectivity, the following reasons could be advanced to argue why an electrochemical scheme would be preferred over a thermal approach (i) There are experimental parameters (pH, solvent, electrolyte, potential) unique only to the electrode-solution interface which can be manipulated to dictate a certain reaction pathway, (ii) The presence of solvent and supporting electrolyte may sufficiently passivate the electrode surface to minimize catalytic fragmentation of starting materials. (iii) Catalyst poisons due to reagent decomposition may form less readily at ambient temperatures, (iv) The chemical behavior of surface intermediates formed in electrolytic solutions can be closely modelled after analogous well-characterized molecular or cluster complexes (1-8).

The rate equation for a single class of transporters acting on a metabolite is analogous to the Michaelis-Menten equation, except that one must also account for the effects of passive diffusion ... [Pg.448]
