Effect Of High Temperature On Metals And Semiconductors

Abstract

The electrical property of noble mineral ( platinum( 58 680 sample and semiconductor 586 821were studied , at temperatures up to 100C0, 373 Kelvin. It was found that the temperature increases mineral resistivity and decreases it is conductivity ,the resistance and conductivity f or the mineral we found to be equal to R = 106.3 Ω and σ = 0. 01176 respectively .

The resistance and conductivity for semiconductor were also obtained . It was found that increasing temperature decreases resistance and increasing of conductivity. Where the resistance and conductivity valves are

. R= 1 Ω and 8.99 respectively. The result conforms with theoretic.
