Latest Patents

One of his latest inventions is a terahertz electromagnetic wave conversion device. The purpose of this invention is to enhance the efficiency of conversion between terahertz electromagnetic wave energy and direct current energy through plasma waves. This device features a high electron mobility transistor (HEMT) structure that includes a substrate, an electron transit layer, an electron supply layer, a source, and a drain. It also incorporates a first and second group of gates, where the gate length of each finger in the first group is narrower than that of the second group. The unequal lengths of the distances from each finger of the first group to adjacent fingers of the second group are also a notable aspect of this invention.

Another significant patent is the complementary logic gate device. This device is represented by a silicon CMOS logical circuit among semiconductor integrated logical circuits. It effectively addresses the speed performance limits of ultra-large scale integration and ultra-low power consumption logical circuits. The complementary logic gate includes an electron running layer formed by graphene, which does not utilize n-channel or p-channel FETs. It features ambipolar characteristics and employs only two FETs with different threshold values, constituting an input and output terminal configuration.
