Who we are...

Under the direction of Professor David Gidley the Michigan NanoPos group studies nano-scale defects and open volumes in condensed matter using positron annihilation spectroscopies.  Our facilities include a bulk-Positron Annihilation Lifetime Spectroscopy (PALS) system and several positron beams located in the Department of Physics. We can perform beam-based PALS and beam-based Doppler Broadening Spectroscopy (DBS).  Beam-based PALS has proven to be a powerful technique for characterizing the pore structure in porous thin films, especially low-k (dielectric) films. Our variable energy positron beams can depth-profile thin films.  For a review of the PALS technique in characterizing porous materials, please see this review paper. We welcome collaborative opportunities.
