MATERIALS SCIENCE Effect of Hydrogen on Amorphous Silicon. J. J. Hauser, Solid State Commun., 19 (1976), pp. 1049-1051. Amorphous Si films prepared by dc sputtering in hydrogen-- argon mixtures possess a high resistivity 1010 fl-cm) similar to that of films prepared by the glow discharge decomposition of silane. PHYSICS Distribution Coefficient of P for Growth of Gai- x Al x Asi_yP v by LPE Determined Using Auger Spectroscopy. C. C. Chang, M. B. Panish, W. R. Wagner, D. L. Rode, S. Sumski and R. G. Sobers, J. Appl. Phys., 47 (1976), pp. 3752-3753. 

Auger spectroscopy was combined with ion milling for quantitative chemical analysis and depth profiling to measure the effective distribution coefficient of phosphorus, k p , during growth of Gai-*Al x Asi- v Py by liquid phase epitaxy. Below y = 0.02 (with x = 0.36), and with cooling rate of 0.1°C/niin for growth, k,, was 290 at growth temperature of 790°C and constant down to at least y = 0.002. This nigh value of kp caused depletion of P from the growth solution. Implications of Radiative Equilibrium in Neoclassical Theory. F. R. Nash and J. P. Gordon, Phys. Rev. A, Gen. Phys., 12, No. 6 (December 1975), pp. 2472-2486. 

It is found tbat the description of spontaneous emission provided by the neoclassical extension of semiclassical electrodynamics, which has been given by Jaynes and his collaborators, is inconsistent with the well-secured laws of Boltzmann and Planck for conditions of thermal equilibrium.
