The Conductivity of metals decreases with increasing Temperature. However, The conductivity of semiconductors increases. Explain these two trends.
Resistance in metals increases with increasing temperature according to the equation, ρ(T) = ρo(1 + α(T - To)) where α is the temperature coefficient of resistivity and ρo is the resistivity at temperature To. For a particular wire α = 1.5 × 10-3 1/°C and
Resistance in metals increases with increasing temperature according to the equation, ρ(T) = ρo(1 + α(T - To)) where α is the temperature coefficient of resistivity and ρo is the resistivity at temperature To. For a particular wire α = 1.5 × 10-3 1/°C and the resistivity is ρo = 8.5 × 10-7 Ω⋅m at To = 125 °C.
