metallipuolijohdeliitos
Metallipuolijohdeliitos, also known as a metal-semiconductor junction, is an electrical contact between a metal and a semiconductor material. The behavior of this interface is crucial in the operation of many electronic devices. When a metal and a semiconductor are brought into contact, charge carriers can accumulate or deplete at the interface, forming a Schottky barrier. The nature of this barrier, whether it is rectifying or ohmic, depends on the work functions of the metal and the semiconductor, as well as the doping concentration of the semiconductor.
A rectifying junction, known as a Schottky diode, exhibits diode-like behavior, allowing current to flow primarily
An ohmic contact, on the other hand, allows current to flow easily in both directions with minimal
