Applications in Semiconductor and Electronic Devices

Another field of application for boron nitride is its use as blocking layer and/or surface layer in electrophotographic photoreceptors [69 to 96,380]. Again, these layers are produced by the CVD methods described in Section 4.1.1.10.2, p. 62. Depending on the deposition method or specific conditions, the boron nitride layers in the electrophotographic receptors may also consist of or contain p-BN [97 to 100]. 

A boron nitride film is applied between the transparent conductive SnOg layer and the amorphous silicon layer in photoelectric solar cells, thus preventing Sn and O diffusion [101].
