The main element in most semiconductor devices is the pn junction, ie the transition layer at the boundary separating the regions with n-type and p-type electrical conductivity in one and the same semiconductor single crystal.

The potential difference at the junction, which is conditioned by the presence of the load-bearing concentration gradient, is called the contact potential barrier. Typical values ​​of the contact potential barrier are in the order of tenths of a volt.

This guide of practical works for the discipline "Electronic Devices" is intended for students with specialties: Telecommunications; Optoelectronic systems; Telecommunications engineering and management, part-time and part-time study forms.
