Welcome to the Zeng lab

Welcome to the Zeng Lab, a condensed matter physics experiment group based at Purdue University, west Lafayette. We are excited about studying and manipulating quantum properties stemming from strong electronic correlations and nontrivial topology in two-dimensional (2D) materials. Our experimental approach includes two parts: 1. We design and fabricate complex nanodevices by stacking 2D crystals into heterostructures in our own lab (just like playing with single-atom-thick Lego pieces) followed by nanofabrication processes in the Birck Nanotechnology Center. 2. We employ a suite of electrical and optical characterization tools to detect the quantum properties of the 2D nanodevices we build—at extremely low temperatures.

Our research aims to discover new physics phenomena and address long-standing questions in physics. Taking one step further, harnessing these quantum properties can drive technological breakthroughs, such as building quantum computers.
