%0 Journal Article %T Solutions for the amorphous silicon system and related problems %A Walter Allegretto %A Yanping Lin %A Aihui Zhou %J Electronic Journal of Differential Equations %D 1998 %I Texas State University %X We present existence of solutions and other results for the partial differential equation system with memory which models amorphous silicon devices and related problems in ${Bbb R}^3$. Our approach employs only classical estimates and Degree Theory; it shows the existence of $C^{alpha,alpha/2}$ solutions for some $alpha>0$. In view of the mixed boundary conditions, this is the maximum regularity that can be expected. %K Reaction %K diffusion %K semiconductor %K Holder continuoussolutions. %U http://ejde.math.txstate.edu/conf-proc/01/a1/abstr.html
