Doug Bonn Condensed matter physics
Doug Bonn’s main area of research is the study of high temperature superconductors, particularly their electromagnetic properties at microwave frequencies. The screening and absorption of electromagnetic radiation at these low frequencies provide some of the key means of probing the pairing state of electrons in superconductors, and the excitations out of that superconducting groundstate. These measurements have provided key information on the d-wave pairing state of the 93 Kelvin superconductor YBCO and continue to reveal new phenomena as we develop samples of increasing perfection and doping control. The materials aspect of the research program at UBC also connects Bonn and his colleagues to numerous other experiments worldwide. The ultimate motivation of this program is to help understand the origin of high temperature superconductivity, a major unsolved problem in condensed matter physics. Closely connected to this is a program of research aimed at the application of the high temperature superconductors in wireless communications. This work on high Tc superconductors is part of a broad collaboration at UBC (Hardy, Liang, Carolan, Brewer, Kiefl, Eldridge) and with other researchers throughout North America. The preparation of state-of-the-art crystals of high Tc superconductors has placed this group at the forefront of research into the fundamental properties of these materials, involving these individuals in numerous collaborations with researchers who make use of materials grown at UBC.
