Researchers in the Fan group have developed a method for epitaxial growth of double heterojunction semiconductor diodes capable of suppressing parasitic non-radiative recombination effects.
Despite widespread adoption of stationary wireless charging, dynamic wireless power transfer suffers from a sensitivity to relative movement of the device with respect to the power source.
Stanford researchers developed a wireless power transfer mechanism that will charge devices while on the move, or in use. The mechanism uses a parity-time symmetric circuit incorporating a nonlinear gain saturation element.
Stanford researchers at the Fan Group have designed and tested a highly efficient radiative cooler prototype with the following record-breaking performance results:
