Welcome to UTSA Nanoelectronics Lab

We, the UTSA Nanoelectronics Lab, are a research group led by Prof. Ethan Ahn in the department of Electrical and Computer Engineering (ECE) at The University of Texas as San Antonio (UTSA). Our research focuses on emerging nanoscale materials and devices technology, exploring such topics as (but not limited to)


  • Energy-efficient logic and memory devices for future computing paradigm

  • Carbon-based and other nanoscale low-dimensional materials (e.g. CNT, graphene, Transition Metal Dichalcogenide, etc.)

  • Experimental and computational exploration of emerging nanoscale devices with emphasis on carrier transport (electron/phonon/spin)

  • Beyond-Si CMOS electronics including spintronics, steep-subthreshold (< 60mV/decade) electronics, energy conversion/harvesting (thermoelectrics) 


Our research laboratory is located in the Durango building in the UTSA downtown campus, and we focus on a wide range of experimental studies including synthesis of novel materials, micro/nano device fabrication, and electrical testing/characterization. We also work on computational nanotechnology (modeling and simulation of various nanoscale devices) to guide and support experimental research at the fundamental scaling limit.

Tackling the limitations of the conventional computing systems using emerging nanomaterials and nanodevices
Microfabrication of a variety of biomedical devices (microneedles, microfluidic sensors, etc.) in commercial, industrial, and military settings
Energy harvesting from 2D nano-materials such as graphene, molybdenum disulfide and phosphorene deposited on top of a flexible substrate
