THERMOELECTRIC RADIATION DETECTOR

摘要: PROBLEM TO BE SOLVED: To extend the available operating temperature range while enhancing detection sensitivity by substituting a rare earth metal for at least part of Y and/or heavy Ba in plurality regions YBa2 Cu3 O7 film. SOLUTION: In crystal solid material film 2 deposited on silicon substrate 1, example, metal, e.g. praseodymium Pr, is substituted yttrium or an alkaline substituted, addition, barium Ba. Alternatively, may be copper Ce. When Pr Y, concentration set 2-40%. This arrangement realizes radiation detector having high and wide operational range.
