We are conducting research on intelligent semiconductor devices for cognitive computation that can recognize objects by mimicking the way the human brain operates. Research on devices that mimic the human brain is being conducted in various ways, and our research team started with artificial intelligence research using resistors, research using electron spin, implementation of devices using oxide semiconductor transistors, and the realization of artificial intelligence devices using low-dimensional materials is a major research topic.

One of the other research interest is elucidating  quantum transport behaviors in nanoelectronic devices by conducting novel experiments including high frequency and low temperature techniques. We are investigating a method to detect spin orbital qubits in InAs nanowire single and double quantum dots using RF reflectometry. We perform shot noise measurements using a superconducting microwave matching circuit that can investigate information about electron transport in nanodevices.

We are also conducting research on heat generation that occurs while driving semiconductor devices. Heat generation in semiconductors can cause fatigue breakdown of the device, which can cause abnormal device operation, and can promote an increase in power consumption. We are analyzing the location of the heating part and the cause of the heating in the operation of the device. In particular, we study the thermal phenomena of semiconductors that could not be analyzed before through thermal analysis with sub-micro level spatial resolution.
