The Princeton Institute of Materials operates the Imaging and Analysis Center (IAC) and the Micro/Nanofabrication Center (MNFC), two large scale multi-user central research facilities at Princeton University. Imaging and Analysis Center The IAC, directed by Dr. Nan Yao, offers a wide range of materials and structural characterization techniques, such as scanning and transmission electron microscopy (including an environmental scanning electron microscope and cryogenic electron microscope for biological materials), focused ion beams, scanning probe microscopy, x-ray diffractions, etc. Micro/Nanofabrication Center The MNFC provides a complete set of tools for designing, fabricating, prototyping and testing a wide range of micro and nano structures and devices, with substrates ranging from traditional silicon and compound semiconductor substrates to flexible metal and plastic foils in a cleanroom environment. The MNFC has a dedicated soft materials processing cleanroom lab as well as an external packaging lab for device integration. Both facilities are professionally staffed, offer extensive training, and are open to all members of the Princeton community as well as external users for an hourly rate. For further information, prospective external users should contact the Institute's Executive Director Alex Norman.
