Diodes [2] In simple terms, a diode is a device that restricts the direction of flow of charge carriers (electrons in this class) [1]. Essentially, it allows an electric current to flow in one direction, but blocks it in the opposite direction. Thus, the diode can be thought of as an electronic version of a check valve.

An anode collects the electrons and puts them to use. Semiconductor Diode Definition: A semiconductor diode is the result of the fusion between a small N-type crystal and a P-type crystal, Figure 1. At the junction of the two crystals, the carriers (electrons and holes) tend to diffuse. Some electrons move across the barrier to join holes.

5x NOS Mullard OC75 germanium diodes/transistors PLEASE READ. These OC75 transistors have been wired as diodes at the factory with the base and collector tied together (see pictures), they might still be useable as transistors when desoldered carefully, but I can't offer any guarantee on that, hence the lower price.
While most of the semiconductor industry concentrated on manufacturing germanium transistors and diodes during this decade, BTL spent most of its research dollars on silicon devices. This research, coupled with the response by the rest of the industry, led to the development of the surface-stabilized silicon transistor and diode, …
During World War II, the company made magnetron tubes and radar systems. Raytheon started making germanium-based semiconductor diodes in the 1940s and, just months after BTL announced the development of the transistor in late 1947, started making its own point-contact transistors using germanium salvaged from …

Germanium Diodes typically have a lower forward voltage drop of around 0.2 to 0.3 volts, while Silicon Diodes have a higher forward voltage drop of around 0.6 to 0.7 volts. This lower forward voltage drop of Germanium Diodes makes them suitable for low voltage applications, where minimizing the voltage drop is crucial.
Overall, silicon is cheaper than germanium. The only disadvantage of silicon in comparison to germanium is that the cut-in voltage of silicon diode is 0.7 volts, while the knee voltage or cut-in voltage of germanium diode is 0.2 volts. This means a higher voltage is required for the conduction of silicon. But considering the advantages listed ...
A diode is a two terminal electrical device. Diodes are made from a semiconductor, most often silicon but sometimes germanium. There are various types of diodes, but the ones being discussed here are Zener, Rectifier, Schottky, Transient Voltage Suppressor, Thyristor, Silicon Controlled Rectifier, and TRIAC. The select gate of the transistor is ...
When focusing on performance, both elements have their own set of pros and cons as semiconducting materials within diodes and transistors. A germanium diode showcases a lower voltage drop compared to a silicon one due to its smaller energy gap which permits electrons to roam about freely at ambient temperature. However, what is …
