Dr. Greg Szulczewski from the University of Alabama will present “Spin and charge transport across organic/inorganic interfaces” to the department.
In this talk I will introduce the research field known as “organic spintronics”.1 It envisioned that spin-dependent electrical conduction in organic-based semiconductors, rather than traditional charge transport, can be used to fabricate low-power, non-volatile, multifunctional devices because electron spin coupling to orbital angular momentum and nuclear spin is weak in low atomic number elements (e.g. carbon).
The focus of this talk will be on the measurement of magnetoresistance and spin-polarized electron tunneling through thin films of organic semiconductors and self-assembled monolayers. To support the interpretation of the electrical/magnetic measurements, significant attention will be devoted to device fabrication and characterization of the interfaces by surface sensitive spectroscopy/microscopy techniques.
