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 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.
Our experimental approach includes two parts: 1. 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.
