Undergraduate Research Opportunities:

   Undergraduate students are participating in our research work through taking ME497, Independent Research, or Summer Undergraduate Research Fellowships (SURF). Previously accomplished ME497 projects include pulsed laser deposition of diamond-like-carbon films, laser micro-machining of metals, photo-deflection measurement of thermal properties, and laser hardening of metals. Email Prof. Xu for more details.

  Please note summer internships are not available for international students not in the US at the time of application.

     

Information for M.S. and Ph.D. applicants:

 

We look for highly motivated students with background in one or more of the following areas:

-        Mechanical Engineering, including Heat Transfer, Thermal Science, Precision Instruments, and Manufacturing

-        Electrical Engineering in Ultrafast Optics

-        Physics, particularly in Solid State Physics and Optics

-        Laser manufacturing and laser diagnostics

-        Microfabrication, i.e., lithography

 

Typical successful applicants in the past had solid background and excellent academic record in his field of study, in addition to meeting the minimum requirement of the ME graduate school.

 

 

Note for International Applicants: Exceptions could be made if your GRE scores do not meet the minimum requirements of the ME graduate school. However, one must demonstrate exceptional accomplishments in other areas. For more information, please contact Prof. Xu

 

Current Open Positions:

 

1. Ultrafast energy transfer in nanomaterials. This project utilizes an ultrafast laser system to investigate electron and phonon transport processes in nanoscale materials, such as supperlattices and quantum dots typically used for solar and thermoelectric energy conversion applications. Background and prior experience in one of the following areas are desirable: heat transfer, solid state physics, and ultrafast laser/optics.

 

2. Laser-based nanomanufacturing.     This project is to develop an optical antenna based parallel nano-  manufacturing system. We have developed nanoscale optical antenna for concentrating light into a nanoscale domain, which in this project are used as light sources for nano-lithography. There are possibly multiple positions in the following areas: optics and/or optical measurement techniques (NSOM), microfabrication, and nano-manufacturing. Background and prior experience in one of the following areas are desirable: optics (experiments or numerical simulations), photo-lithography, laser, and NSOM.

 

3. Laser-guided nanowire growth. This is collaborative project with Professors in Chemistry, ECE, MSE, and Physics to develop a laser-based nanowire growth method. We use nanoscale optical antenna (see 2 above) for concentrating light into a nanoscale domain, and use the nanoscale light spot to precisely direct the growth of nanowires. There are possibly multiple positions in areas of nano-optics, precision instrumentation and CVD based nanowire growth. Background and prior experience in one of the following areas are desirable: optics (experiments or numerical simulations), laser, micor/nano lithography, and CVD growth of nanomaterials.
