To quantify the influence of crystal dislocations on materials electrical, optical, magnetic, thermoelectric, superconducting properties with one single unified analytical theory, with no empirical fitting parameter.
From dislocation to dislon
Electron energy can oscillate near and edge but not screw dislocation
Dislocation-phonon Interaction: Solving decades-long debate
Advantages of dislon approach
Dislocated superconductor’s mechanism
Non-perturbative dislocation-phonon interaction
Resonance peak of phonon relaxation rate when interacting with phonons indicates a breakdown of all perturbation theory.
Dislocation induced superconductivity
Dislon, as quantized dislocation, as a unified theoretical framework, opens up numerous opportunities to quantify the quantum and functional properties in dislocated crystals, at a full quantum-field-theoretical level.
The authors dedicate this poster to Prof. Mildred S Dresselhaus for her support on this study.
