What type of band is both Wire and Electrasy considered?
Wire (band) Wire are an English rock band, formed in London in October 1976 by Colin Newman (vocals, guitar), Graham Lewis (bass, vocals), Bruce Gilbert (guitar) and Robert Gotobed (drums). They were originally associated with the punk rock scene, appearing on "The Roxy London WC2" album – a key early document of the scene – and were later central to the development of post-punk.
I-III-VI semiconductors I-III-VI semiconductors are solid semiconducting materials that contain three or more chemical elements belonging to groups I, III and VI of the periodic table. They usually involve two metals and one chalcogen. Some of these materials have a direct bandgap, E, of ~ 1.5 eV, which makes them efficient absorbers of sunlight and thus potential solar cell materials. A fourth element is often added to a I-III-VI material to tune the bandgap for maximum solar cell efficiency. A representative example is copper indium gallium selenide (CuInGaSe, E = 1.7–1.0 eV for x = 0–1), which is used in copper indium gallium selenide solar cells.
