A homojunction is a semiconductor interface that occurs between layers of similar semiconductor material; [1] these materials have equal band gaps but typically have different doping. In most practical cases a homojunction occurs at the interface between an n-type ( donor doped) and p-type ( acceptor doped) semiconductor such as silicon , this ...
A laser diode (LD, also injection laser diode or ILD or semiconductor laser or diode laser) ... The first diode lasers were homojunction diodes. That is, the material ...
In semiconductor laser theory, the optical gain is produced in a semiconductor material. The choice of material depends on the desired wavelength and properties such as modulation speed. It may be a bulk semiconductor, but more often a quantum heterostructure. Pumping may be electrically or optically . All these structures can be described in a ...
The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details). Most of the data comes from Weber's book Handbook of laser wavelengths, [1] with newer data in particular for the semiconductor lasers.
These semiconducting materials have unequal band gaps as opposed to a homojunction. It is often advantageous to engineer the electronic energy bands in many solid-state device applications, including semiconductor lasers, solar cells and transistors.
It's one of several companies benefiting from AI invigorating the global semiconductor industry, with its AI revenue growing 220% this year," said eMarketer analyst Jacob Bourne.
A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
(The Center Square) – Puget Sound leaders and union heads are demanding better protections for bus drivers after a King County Metro driver was recently killed. Early Wednesday morning, driver ...
