>Silicon is a semi-conductor, but the principal is the same. Afaik temperature dependence of materials is a more complicated relation than this. The graph of their coefficient does not even need to be monotone and can change depending on what properties dominate. E.g. a semiconductor can have NTC because charge concentration increases with the temperature, however when it reaches saturation this effect diminishes and it will behave similar to a regular PTC conductor. https://en.wikipedia.org/wiki/Temperature_coefficient#Negative_Temperature_Coefficient_of_Resistance_Of_a_Semiconductor https://en.wikipedia.org/wiki/Temperature_coefficient#Negati...
