Amorphous silicon (a-Si) is the non-crystalline form of silicon used for solar cells and thin-film transistors in LCDs. Used as semiconductor material for a-Si solar cells, or thin-film silicon solar cells, it is deposited in thin films onto a variety of flexible substrates, such as glass, metal and plastic. Amorphous silicon cells generally feature low efficiency. As a second-generation thin-film. DescriptionSilicon is a fourfold coordinated atom that is normally bonded to four neighboring silicon atoms. In crystalline silicon (c-Si) this tetrahedral structure continues over a large range, thus forming a well-orde. .
Amorphous of silicon and carbon (amorphous silicon , also hydrogenated, a-Si1−xCx:H) are an interesting variant. Introduction of carbon atoms adds extra degrees of freedom for control of th. .
The density of a-Si depends on preparation conditions, for example, for electron beam evaporated films the density depends on thickness, growth temperature and rate, ranging from 3.90×10 to 4.95×10 atom/cm (1.82 to 2.3.

A common use of the H-bridge is an . The arrangement is sometimes known as a single-phase bridge inverter. The H-bridge with a DC supply will generate a square wave voltage waveform across the load. For a purely inductive load, the current waveform would be a triangle wave, with its peak depending on the inductance, switching frequency, and input voltage.

Electroshock weapon technology uses a temporary high-voltage, low- electrical discharge to override the body's muscle-triggering mechanisms. Commonly referred to as a stun gun, electroshock weapons are a relative of , which have been around for over 100 years and are the precursor of stun guns. The recipient is immobilized via two metal probes connected via wires to the electroshock device. The recipient feels , and can be momentarily paralyze.
