✦ Synopsis


The plasma spray technique was used to obtain p-type polycrystalline silicon deposits 200 #m -2 mm thick and of area 1 cm 2. Silicon layers 50 #m thick were grown on these deposits by chemical vapour deposition. The electronic diffusion length of plasma-sprayed silicon was found to be in the range 9-16 pm whereas it increased to 28 pm in the layer grown by chemical vapour deposition.
