    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).

  4. Silicon–germanium - Wikipedia

    en.wikipedia.org/wiki/Silicongermanium

    SiGe (/ ˈ s ɪ ɡ iː / or / ˈ s aɪ dʒ iː /), or silicongermanium, is an alloy with any molar ratio of silicon and germanium, i.e. with a molecular formula of the form Si 1−x Ge x. It is commonly used as a semiconductor material in integrated circuits (ICs) for heterojunction bipolar transistors or as a strain -inducing layer for CMOS ...

  5. Transistor - Wikipedia

    en.wikipedia.org/wiki/Transistor

    The prefix is followed by a two-, three- or four-digit number with no significance as to device properties, although early devices with low numbers tend to be germanium devices. For example, 2N3055 is a silicon n–p–n power transistor, 2N1301 is a p–n–p germanium switching transistor. A letter suffix, such as "A", is sometimes used to ...

  6. Nanowire battery - Wikipedia

    en.wikipedia.org/wiki/Nanowire_battery

    A nanowire battery uses nanowires to increase the surface area of one or both of its electrodes, which improves the capacity of the battery. Some designs (silicon, germanium and transition metal oxides ), variations of the lithium-ion battery have been announced, although none are commercially available.

  7. Heterojunction solar cell - Wikipedia

    en.wikipedia.org/wiki/Heterojunction_solar_cell

    A silicon heterojunction solar cell that has been metallised with screen-printed silver paste undergoing Current–voltage curve characterisation An unmetallised heterojunction solar cell precursor. The blue colour arises from the dual-purpose Indium tin oxide anti-reflective coating, which also enhances emitter conduction.

  8. Theory of solar cells - Wikipedia

    en.wikipedia.org/wiki/Theory_of_solar_cells

    For most crystalline silicon solar cells the change in V OC with temperature is about −0.50%/°C, though the rate for the highest-efficiency crystalline silicon cells is around −0.35%/°C. By way of comparison, the rate for amorphous silicon solar cells is −0.20 to −0.30%/°C, depending on how the cell is made.

  9. Solaristor - Wikipedia

    en.wikipedia.org/wiki/Solaristor

    The two-in-one transistor plus solar cell achieves the high-low current modulation by a memresistive effect in the flow of photogenerated carriers. The term was coined by Dr Amador Perez-Tomas working in collaboration with other ICN2 researchers in 2018 when they demonstrated the concept in a ferroelectric-oxide/organic bulk heterojunction ...
