Our lab specializes in tailoring new materials and their processing for advancing cutting edge technologies. This includes the growth of new layered 2D materials, the modification and tailoring of their properties for device applications, and the processing of novel devices from them. Our research combines synthetic chemistry, device processing, theoretical and computational methodologies. The Naveh group also experts in developing new, advanced electronic and optoelectronic measurements and characterization techniques and the use of advanced methods for processing the acquired data.
