Jeremy Tisdale is a fifth-year Ph.D. student in the Materials Science and Engineering Department at the University of Tennessee, Knoxville, who is expecting to graduate in December 2018. Mr. Tisdale previously received his Bachelor of Science and Master of Science from the Materials Science and Engineering (MSE) Department at the University of Tennessee in 2013 and 2016, respectively. His master’s research focused on magneto-optical behaviors at ferromagnetic/organic semiconductor interfaces. With the recent explosion of interest in organometallic halide perovskites, Mr. Tisdale is focusing his Ph.D. research under the guidance of Dr. Bin Hu on the development of organic-lead halide perovskite single crystals towards high-resolution, room temperature gamma-ray sensing. This research includes synthesis of single crystalline methylammonium lead halide perovskites and optimization of growth techniques towards high optoelectronic quality crystals. After synthesis, post-growth treatments and characterization of bulk and surface properties through photoluminescence, current-voltage characteristics, impedance spectroscopy, XRD, etc., are vital to understanding the optoelectronic properties and mechanisms inside the single crystals for high-resolution sensing. Once high-quality crystals are grown, research moves towards device fabrication to be tested for high energy radiation sensing performance. Recent work in this area on interfacial properties between metals and single crystal hybrid perovskites has been published in Advanced Materials Interfaces, with additional work on the synthesis of organometallic hybrid perovskite single crystals under review in other high impact journals.
Mr. Tisdale has also been a co-author on several recently published journal articles in his research group, including studies focused on the Seebeck effect in organic thermoelectric devices, magnetic Seebeck effect studies, and magneto-electric coupling in organic-inorganic hybrid systems.
