As its name implies, the Light Dependent Resistor (LDR) is made from a piece of exposed semiconductor material such as cadmium sulphide that changes its electrical resistance from several thousand Ohms in the dark to only a few hundred Ohms when light falls upon it by creating hole-electron pairs in the material.

A Zener diode is a special type of diode designed to reliably allow current to flow "backwards" when a certain set reverse voltage, known as the Zener voltage, is reached. ... Zener diodes are widely used in electronic equipment of all kinds and are one of the basic building blocks of electronic circuits.

Although there are many different types of diode which use the same basic structure of an area of p-type material meeting an area of n-type material, the different types are optimised to provide different characteristics which can be used in a variety of ways in many electronic circuit designs.

Fuse Wire Materials. The material used for fuse elements must be of low melting point, low ohmic loss, high conductivity (or low resistivity), low cost and free from detraction. The material used for making fuse element has a low melting point such as tin, lead, or zinc.

A diode vacuum tube or thermionic diode is a vacuum tube with two electrodes, a heated cathode and a plate, in which electrons can flow in only one direction, from cathode to plate. ... Today, most diodes are made of silicon, but other semiconducting materials such as gallium arsenide and germanium are also used.

Commercial Battery Materials Commercially available batteries use a variety of metals and electrolytes. Anodes can be made of zinc, aluminum, lithium, cadmium, iron, metallic lead, lanthanide, or graphite. Cathodes can be made of manganese dioxide, mercuric oxide, nickel oxyhydroxide, lead dioxide or lithium oxide.

CdTe solar cells are completed by adding a high-quality transparent conductive oxide (TCO)—usually fluorine-doped tin oxide (SnO2:F)—and a back electrical contact—typically a metal or carbon paste with copper (Cu).

The main raw material used in semiconductor devices is silicon, which is generally converted into "boules," more commonly known as single-crystal ingots. These ingots are further converted into silicon wafers, as one of the first stages in the chip (integrated circuit) manufacturing process.

Solar cells are made from silicon boules. These are polycrystalline structures that have the atomic structure of a single crystal. The most commonly used method for the creation of the boule is known as the Czochralski method. During this process, a seed crystal of silicon is dipped into melted polycrystalline silicon.
