There is substantial interest in developing new classes of semiconductor and thermoelectric materials exploiting the properties of bismuth. Such materials are increasingly important for the development of optoelectronic, thermoelectric and electronic devices. These include materials for laser diodes, light emitting diodes, solar cells, transistors and spintronic devices. Following on the success of the previous four annual international workshops on bismuth-containing materials, held in Michigan, Surrey, University of Victoria and Arkansas, this meeting will bring together groups undertaking research in the emerging area of bismuth-containing materials and devices for a focused three-day workshop. This is an interdisciplinary meeting bringing together physicists, chemists, materials scientists and engineers to address this important emerging area. Topics will focus on theoretical activities, epitaxial growth, characterization (optical, electrical and structural) and device performance of interest to both academic and industrial researchers.
