Semiconductor Thermometers Classification of Semiconductor Thermometers Semiconductor thermometers (Sachse, 1975) are made from materials which are neither conductors nor insulators. Research of the thermal properties of semiconductors was first reported by William Faraday in 1834. Their industrial production was started at the Bell Telephone Company and, simultaneously, at Osram in 1930. It is apparent from the work of many authors such as Sze (1969) and van der Ziel (1968), among others, that these materials may have an intrinsic, or pure form, a compound form or a doped form. Compound and doped semiconductors are often called extrinsic semiconductors ....
