Low-dimensional materials and devices

At our lab, we investigate the electrical, optical, and optoelectronic phenomena that emerge in low-dimensional condensed matter systems. On the one hand, we study the properties of van der Waals inorganic materials when reduced to just a few atomic layers, which offer unique opportunities for the development of two-dimensional devices. On the other hand, we explore the properties of thin films of engineered biomaterials that show promise for creating biocompatible nano- and micro-devices. By studying the responses of these materials and their hybrid structures to external fields and light, we aim to gain insight into their fundamental electronic and optical properties that can impact applications in electronics, optoelectronics, and spintronics.

Photoluminescence and photocurrent generation coexist in FePS3/1L-MoS2 heterostructure devices. Their interplay can be tuned through the application of small bias voltages, providing a simple means to control the device’s light emission. Find our work in Nanoscale Advances.
