Research Synopsis: Our research is conducted at the convergence of two central areas of nanoscience — nanophotonics and nanomechanics. We develop nano-electro-mechanical systems (NEMS) and nano-opto-mechanical systems (NOMS) to explore their novel properties in both classical and quantum regimes. We study the coupling and interaction between electrical, optical and mechanical degrees of freedom (electrons, photons and phonons) in nanoscale devices. We employ state-of-the-art top-down or bottom-up approaches to fabricate devices and structures with various semiconductor and dielectric materials. We utilize integrated photonic circuits as optical breadboards to investigate optoelectronic phenomena in novel materials including graphene and other emerging 2D crystals. Our interest spans from the measurement of fundamental physics parameters with the highest precision that is only bounded by the law of nature, to development of novel devices for radio-frequency, microwave and optical communication and computation, and to building tools for chemical and biological sensing, medical diagnostics and neuroscience.

Positions Available:

  • Postdoctoral Researcher (one immediate opening)
  • We are seeking a self-motivated postdoctoral researchers to join our group to work on the topics of 2D material (graphene, 2D transistion metal chalcogenides(MX2)) based optoelectronics. Priorities are given to candidates with strong backgrounds, both experimental and theoretical, in ultrafast optics, nonlinear optics, device design and fabrication. Other experiences in nanofabrication, photonic bandgap structure design, AMO physics and quantum optics are advantageous. Interested candidates please send a CV and a research statement to Professor Mo Li: limo.umn@gmail.com.

  • Graduate Students (immediate openings, spring admission possible)
  • We have several openings for graduate research assistants. Prospective graduate students interested in joining our research group should apply to the PhD program in the Department of ECE, University of Minnesota. An undergraduate degree in electrical engineering, physics, applied physics or related fields is required. Experiences and skills in nanophotonics, numerical simulation, nanofabrication, and instrument design are encouraged. Admission for the spring semesters is also possible. To apply, send an email including a CV and a research statement to Professor Mo Li (limo.umn@gmail.com).
