Steady Floquet–Andreev states in graphene Josephson junctions

Spintronic filter via p-typed polaron state in photoelectron conversion integrating devices

“…Generally, the spin directions of excited electrons are rarely considered under light irradiation without specific angular momentum modulation. However, the development of quantum electronic devices requires the spintronic with modulable angular momentum to solve the Floquet state, 12 which is a non-equilibrium quantum state induced by monochromatic light.…”

“…10 Spintronic injection devices are considered to have a promising design in enhancing the performance of electronic devices via high charge mobility and low electron accumulation. 11 Thus, to achieve commercial quantum electronic devices 12 and sustain the accuracy of the devices in performance modulation, low-cost and high-defect tolerance materials are the basic requirements, along with the ability for high spin polarization to achieve spin-orbital coupling 13,14 and spintronic excitation. In some research, 2D hybrid metal halides were prepared to accomplish ultrafast spintronic excitation and high spin current density.…”

Multi-terminal Josephson junctions: A road to topological flux networks

“…Indeed, these devices may reveal non-Abelian Berry curvatures and higher-order Chern numbers in their non-linear response or through microwave spectroscopy. Another twist might come from the recent realization of Floquet ABS in a graphene JJ [54] which could bring the possibility of Floquet engineering into the field.…”

Monolayers of Germanene/Janus Ga2SeTe van der Waals Heterostructures by First-Principles Calculations for High-Performance Optoelectronic Devices

“…Since graphene was discovered by Geim and Novoselov in 2004, it has become a research hotspot in the fields of condensed matter physics, − catalysis, , energy, , and optoelectronics. , Graphene has excellent physical properties, including Dirac cones, ultrahigh mobility, quantum Hall effect, etc., which have broad device application potential. Researchers are gradually turning their attention to two-dimensional (2D) nanomaterials with a graphene-like structure.…”
