WebIn this work, we introduce an electronic mechanism for spin-triplet superconductivity in doped insulators, where the pairing of doped electrons arises from interband electronic effects. By developing a controlled hybridization expansion, we show that an attractive interaction between two conduction electrons arises from virtual interband ... WebThe spintronics of excitons is key to our work. Indeed, the high efficiencies of singlet exciton fission arise because competing thermalization losses are spin disallowed. Figure: Unlike electrons, excitons can be split. In the Center for Excitonics, we have used singlet exciton fission in pentacene to generate at least 1.26 electrons per photon.
WebFeb 9, 2024 · In CsPbBr 3 NPls, the strong orbit-spin coupling of conduction band electron mixes the triplet and singlet states, which makes TET between singlet dark exciton and triplet state of mediator possible. WebApr 13, 2024 · The employment of spin polarization under an external magnetic field holds great potential for the improvements of photocatalytic performance. However, owing to the huge difference in dielectric properties between ferromagnetic oxide and polymers, the photogenerated excitons with spin states are often limited to the ferromagnetic oxide …
WebThe Kondo insulator SmB 6 is purported to develop into a robust topological insulator at low temperatures. Yet there are several puzzling and unexplained physical properties of the insulating bulk. It has been proposed that bulk spin excitons may be the source of these anomalies and may also adversely affect the topologically protected metallic surface states.
