BRAINCAKECurrent-Voltage Graph for Thermistors and LDRs
Thermistors are made of semiconductor materials.
Initially there are few charge carriers per unit volume (conduction electrons).
When the temperature increases the electrons that are bound to the atom gains energy and break free so there are more conduction electrons.
