What is SCR? The term SCR or silicon controlled rectifier is often used synonymously with that of thyristor - the SCR or silicon controlled rectifier is actually a trade name used by General Electric. The idea for the thyristor was first described by Shockley in 1950.

- SCR is a Silicon Controlled Rectifier. It is a semiconductor switch that is used to control large amounts of power with small signal input. It is turned off by the current through it, naturally becoming zero.CR stands for Silicon Controlled Rectifier. First, think of a simple diode. This can be thought of as an electronic 'check valve' that only allows current to pass in one direction (assuming, of course, that it is used within its engineering specifications).

Polydimethyl siloxane Polydimethylsiloxane (PDMS) belongs to a group of polymeric organosilicon compounds that are commonly referred to as silicones. PDMS is the most widely used silicon-based organic polymer, and is particularly known for its unusual rheological (or flow) properties.PDMS is optically clear, and, in general, inert, non-toxic, and non-flammable. It is also called dimethicone and is one of several types of silicone oil (polymerized siloxane).DMS is the most widely used silicon-based organic polymer, and is particularly known for its unusual rheological (or flow) properties.

What is an SCR Silicon Controlled Rectifier or Thyristor The silicon controlled rectifier, SCR or thyristor symbol used for circuit diagrams or circuit seeks to emphasis its rectifier characteristics while also showing the control gate. As a result the thyristor symbol shows the traditional diode symbol with a control gate entering near the junction.

Thyristor Tutorial In many ways the Silicon Controlled Rectifier, or the Thyristor as it is more commonly known, is similar to the transistor. It is a multi-layer semiconductor device, hence the “silicon” part of its name.It requires a gate signal to turn it “ON”, the “controlled” part of the name and once “ON” it behaves like a rectifying diode, the “rectifier” part of the name.In fact the circuit symbol for the thyristor suggests that this device acts like a controlled rectifying diode.owever, unlike the diode which is a two layer (P-N) semiconductor device, or the transistor which is a three layer (P-N-P, or N-P-N) device, the Thyristor is a four layer (P-N-P-N) semiconductor device that contains three PN junctions in series, and is represented by the symbol as shown.

Monocrystalline silicon A silicon ingot. Monocrystalline silicon (or single-crystal silicon, single-crystal Si, mono c-Si, or just mono-Si) is the base material for silicon chips used in virtually all electronic equipment today. Mono-Si also serves as photovoltaic, light-absorbing material in the manufacture of solar cells.n 2013, monocrystalline solar cells had a market-share of 36 percent, that translated into the production of 12,600 megawatts of photovoltaic capacity, and ranked second behind the somewhat cheaper sister-technology of polycrystalline silicon.

Silicon carbide Silicon carbide (Si C), also known as carborundum, is a compound of silicon and carbon with chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide powder has been mass-produced since 1893 for use as an abrasive.lpha silicon carbide (α-SiC) is the most commonly encountered polymorph; it is formed at temperatures greater than 1700 °C and has a hexagonal crystal structure (similar to Wurtzite). The beta modification (β-SiC), with a zinc blende crystal structure (similar to diamond), is formed at temperatures below 1700 °C.
