2D metal contacts stop transistor leakage currents in their tracks

Computers, despite all their apparent complexity, are basically just a large number of electronic switches, flicking on and off in the right order to process digital information. Semiconductor technology has made these switches ...

Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency. The period is the duration of one cycle in a repeating event, so the period is the reciprocal of the frequency. For example, if a newborn baby's heart beats at a frequency of 120 times a minute, its period (the interval between beats) is half a second.
