Nan Lab

The NaN (NEMS and Nano-spintronics) Lab is headed by Dr. Tianxiang Nan (南天翔) in the School of Integrated Circuits at Tsinghua University.

About us

Motivated by the CMOS scaling limits, we aim to develop new functional devices and beyond-CMOS systems by harnessing good vibrations and the spin of electrons in solids for communication, memory and sensory applications.

Our research spans from MEMS and spintronics devices, that are powered by advanced materials, to circuits and architectures that enable these devices.
