In another configuration, it is equal to epsilon times epsilon sub naught times A over d.
A quantum version of this quantity for 2D-electron systems is equal to the fundamental charge squared times the density of states; graphene's band structure gives it two values of this quantity. Changes in this quantity are measured in deep level transient spectroscopy. It can be increased using an inverting voltage amplifier by 1 minus A sub v, an effect exploited in pole splitting named for Miller. Its inverse is known as elastance, and for an isolated sphere its equal to four pi epsilon a. In another configuration, it is equal to epsilon times epsilon sub naught times A over d. The SI unit for this quantity is measured in coulombs per volts and is called the farad. For 10 points, name this measure of the amount of electric charge stored in a namesake electronic component.
