Electrical and Spectroscopic Characterization of Thin Films

Understanding the Chemistry behind Carrier Transport Properties of Bulk and Interfacial Regions in Solution-Deposited Films

Many standard physical and chemical characterization techniques are insensitive to low quantities of dopants and defects in solution-deposited thin films. However, electrical characterization (EC) is a powerful and sensitive method for probing these properties. The objective of this group is to use EC to understand how impurities or additives (counterions, condensation byproducts, metal dopants, etc.) affect bulk film chemistry and device interface properties. Therefore a complete suite of complementary electrical characterization techniques focused on elucidating bulk and interfacial chemistry will enhance our understanding of these functional films. This will be done in parallel with standard physical (TEM/SEM, SAXS, XRR/XRD) and chemical (IR, NMR, Raman) characterization techniques to create a complete picture of film structure and the roles of defects.
