Latest Patents

Kexin Li holds a patent for her invention titled "Pulse compression photoconductive semiconductor switches." This patent describes a photoconductive switch that utilizes materials supporting negative differential mobility. The operation of this switch leverages the pulse compression of a charge cloud to generate the 'on' time of the pulse, in combination with the speed of light to create the 'off' time of the pulse. The method involves selecting parameters such as voltage, spot size of a laser pulse, temporal pulse width, and intensity of the laser pulse. These parameters enable the switch to operate in a region where the light-absorbing material exhibits negative differential mobility. The switch is illuminated with a laser pulse to generate a charge cloud within the light-absorbing material.
