that the thermal resistance of the bilayer graphene hot electron bolometer will increase even more so due to the differential increase in \(C_V\). This will decrease the thermal fluctuation noise equivalent power (NEP,) thus increasing the overall performance of the bolometer. If, however, a bias voltage is applied to the bilayer graphene, it is then possible to increase DC conductivity of the bilayer graphene sample. As such, the increase in conductivity will result in a photoconductively induced voltage signal. By setting the temperature close to the CDW phase change temperature, photoconductive response can be increased by roughly an order of magnitude; since the CDW gap in bilayer graphene is about 70meV [11].
 Another possible application stems from the differential resistance of CDW structures around phase change temperatures. We can see from the figure below that CDW transitions are accompanied by negative differential resistance.
