Temperature dependences of resistive properties for both HRS (polarization down) and LRS (polarization down): (a) curves of resistance and On/Off resistance ratio R H/ R L versus temperature; (b) curves of ln( R ) versus 1000/ T , which can be fitted to the Arrhenius equation R ∝ exp(− E a/ k B T ).
