  of $VO_2$ single crystals   The abrupt metal insulator transition in $VO_2$ is attracting considerable
interest from both fundamental and applicative angles. We report on DC I-V
characteristics measured on $VO_2$ single crystals in the two-probe
configuration at several ambient temperatures below the insulator-metal
transition. The insulator-mixed-metal-insulator transition is induced by Joule
heating above ambient temperature in the range of negative differential
resistivity (NDR). In this range the stability of V(I) is governed by the load
resistance $R_L$. Steady state I(V) is obtained for $R_L> |dV/dI|_{max}$ in the
NDR regime. For $R_L< |dV/dI|_{max}$ there is switching between initial and
final steady states associated with peaks in the Joule power, that are higher
the lower $R_L$ is. The peaks caused by steep switching are superfluous and
damaging the samples. On the other hand, the large $R_L$ needed for steady
state is the main power consumer in the circuit at high currents. The present
work is motivated by the need to avoid damaging switching in the NDR regime
while reducing the power consumption in the circuit. It is shown here that
large resistance modulation can be obtained under steady state conditions with
reduced power consumption by increasing the ambient temperature of the device
above room temperature.
