We report the manufacture of novel graphene diode sensors (GDS), which are composed of monolayer graphene on silicon substrates, allowing exposure to liquids and gases. Peak Inverse Voltage Peak inverse voltage (PIV) across the diode: a parameter, which defines the choice of the diode. 6 μm and an interpitch of 2 μm. Also great for conversions (funnel-like). Since the n-type region has a high electron concentration and the p-type a high hole concentration, electrons diffuse from the n-type side to the p-type side. The p-n junction is a versatile element, which can be used as a. , the diode behaves like an ideal short circuit). An on-off switch allows current to flow only when it is in the closed (on) position. Whether they influence the flow of electricity by using voltage or current as the control, active components allow a small input to generate a matching, larger output. In an alternator a much smaller current is fed through the brushes to the rotating field windings, so they last longer. Cody Nascene.
