  2. II-VI semiconductor compound - Wikipedia

    en.wikipedia.org/wiki/II-VI_semiconductor_compound

    Tensions and impurities due to low crystal quality result in low optoelectronic properties. One example of the basic possibilities achievable with three different compounds is shown in the diagram with zinc oxide (ZnO), cadmium oxide (CdO) and magnesium oxide (MgO). Basically it is possible to gain any band gap between those of the three materials.

    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).

    Most multiferroic materials are transition metal oxides due to the magnetization potential of the 3d electrons. Many can also be classified as perovskites and contain the Fe 3+ ion alongside a lanthanide ion. Below is an abbreviated table of common multiferroic compounds. For more examples and applications see also multiferroics.

    For example, a MoS 2 monolayer is only 6.5 Å thick. The key feature of these materials is the interaction of large atoms in the 2D structure as compared with first-row transition-metal dichalcogenides, e.g., WTe 2 exhibits anomalous giant magnetoresistance and superconductivity. [1]

  6. Direct and indirect band gaps - Wikipedia

    Some III–V materials are indirect bandgap as well, for example AlSb. Energy vs. crystal momentum for a semiconductor with an indirect band gap, showing that an electron cannot shift from the highest-energy state in the valence band (red) to the lowest-energy state in the conduction band (green) without a change in momentum.

    The example given, paraffin wax, is a member of a family of hydrocarbon molecules of differing chain lengths, with high-density polyethylene at the long-chain end of the series. High-density polyethylene can be a strong material: when the hydrocarbon chains are well aligned, the resulting fibers rival the strength of steel. The covalent bonds ...
