Transport studies of single-molecule magnet (SMM) vertical heterojunctions.

ORAL

Abstract

Incorporation of single molecule magnets (SMMs) as quantum materials into thin-film heterojunctions is a necessary first step for implementation of useful quantum devices. We present results of our efforts to use independent thermal control of both source and substrate temperatures to obtain fully covered, intact, and well crystallized SMM films on a variety of substrates. The SMM studied is TbPc2 with its quasi-planar double-decker geometry. Characterization by XRD, RAMAN, MOKE, SQUID, and vertical transport allows an assessment of how the SMMs change their electronic and magnetic properties as film thickness approaches monolayer dimensions and interface effects become increasingly important1.
