The semiconductor materials used in electronic devices are doped under precise conditions to control the concentration and regions of p- and n-type dopants. A single semiconductor device crystal can have many p- and n-type regions; the p–n junctions between these regions are responsible for the useful electronic behavior.
Tyagi wrote one internationally acclaimed book Introduction to Semiconductor Materials and Devices, [5] which is widely used in Electrical Engineering, semiconductor devices and material science undergraduate and postgraduate courses. It was published by John Wiley & Sons on 7 March 1991. M. S. Tyagi: Introduction to Semiconductor Materials and ...
Outlines of some packaged semiconductor devices. A semiconductor device is an electronic component that relies on the electronic properties of a semiconductor material (primarily silicon, germanium, and gallium arsenide, as well as organic semiconductors) for its function. Its conductivity lies between conductors and insulators. Semiconductor ...
A semiconductor diode (devices that allow current in only one direction) consists of p-type and n-type semiconductors placed in junction with one another. Currently, most semiconductor diodes use doped silicon or germanium. Transistors (devices that enable current switching) also make use of extrinsic semiconductors.
A two-dimensional semiconductor (also known as 2D semiconductor) is a type of natural semiconductor with thicknesses on the atomic scale. Geim and Novoselov et al. initiated the field in 2004 when they reported a new semiconducting material graphene, a flat monolayer of carbon atoms arranged in a 2D honeycomb lattice. [1]
The term solid-state became popular at the beginning of the semiconductor era in the 1960s to distinguish this new technology. A semiconductor device works by controlling an electric current consisting of electrons or holes moving within a solid crystalline piece of semiconducting material such as silicon, while the thermionic vacuum tubes it replaced worked by controlling a current of ...
Manijeh Razeghi is an Iranian-American scientist in the fields of semiconductors and optoelectronic devices.She is a pioneer in modern epitaxial techniques for semiconductors such as low pressure metalorganic chemical vapor deposition (MOCVD), vapor phase epitaxy (VPE), molecular beam epitaxy (MBE), GasMBE, and MOMBE.
In semiconductor lasers, the carrier lifetime is the time it takes an electron before recombining via non-radiative processes in the laser cavity. In the frame of the rate equations model , carrier lifetime is used in the charge conservation equation as the time constant of the exponential decay of carriers.
