DiodeArrayTechnology/ComputersAndElectronics [Charles M Brown] Diode arrays installed at many power feed points by hybrid attachment among a computer chip's logic and memory subsystems of components will reabsorb operational heat and provide clean and reliable electrical power. Chip power supply pins would then be unnecessary significantly reducing the cost of chips and simplifying the interconnection patterns. The computer case can then be completely sealed and densely packed with many high power chips without consuming much electricity or requiring cooling.
The gain of field effect transistors increases as the temperature decreases and the thermal noise in a communication channel decreases with temperature so the performance of many electronic devices can be improved by cooling them. Diode array output should be proportional to the square of the absolute temperature. Their performance as refrigeration chips is likely to be adequate at low operating temperatures.
Small inexpensive atomic clocks may be possible. I read that Teflon coating the resonator walls made it easier to build up the atomic oscillation at low temperature. Cheap atomic clocks would lead to accurate frequencies in electronic equipment.
