Spin Multiplicity and Solid-State Electrochemical Behavior in Charge-Transfer Co-crystals of DBTTF/F4TCNQ

Charge Transfer in Molecular Crystals.

Spin and Charge Transfer in Selected Nanostructures

The general theme in this thesis is the interplay between electron spin and charge in nanoscale transport phenomena. The main presentation is divided into three independent chapters. In chapter 2, we propose a mechanism that explains the excess damping and dynamic exchange interactions which are observed in ferromagnet/paramagnet hybrids. A moving ferromagnetic magnetization emits spin current ...

Quantum ferroelectricity in charge-transfer complex crystals

Quantum phase transition achieved by fine tuning the continuous phase transition down to zero kelvin is a challenge for solid state science. Critical phenomena distinct from the effects of thermal fluctuations can materialize when the electronic, structural or magnetic long-range order is perturbed by quantum fluctuations between degenerate ground states. Here we have developed chemically pure ...

Semiempirical modeling of electrochemical charge transfer.

Nanoelectrochemical experiments using detection based on tip enhanced Raman spectroscopy (TERS) show a broad distribution of single-molecule formal potentials E°' for large π-conjugated molecules; theoretical studies are needed to understand the origins of this distribution. In this paper, we present a theoretical approach to determine E°' for electrochemical reactions involving a single molecu...

Room Temperature Multiferroicity of Charge Transfer Crystals.

Room temperature multiferroics has been a frontier research field by manipulating spin-driven ferroelectricity or charge-order-driven magnetism. Charge-transfer crystals based on electron donor and acceptor assembly, exhibiting simultaneous spin ordering, are drawing significant interests for the development of all-organic magnetoelectric multiferroics. Here, we report that a remarkable anisotr...
