Advanced Functional Materials, EarlyView.This study presents a new hole transporting material (HTM) mechanism for self‐assembled monolayers in near‐infrared organic photodetectors. The formation of zwitterions induces a strong electric field that significantly increases the work function of HTM‐coated indium tin oxide substrates. The devices exhibit low dark current and noise, along with high

Quantum Field Theory with Dynamical Boundary Conditions and the Casimir Effect
, 2023 We study a coupled system that describes the interacting dynamics between a bulk field, confined to a finite region with timelike boundary, and a boundary observable. In our system the dynamics of the boundary observable prescribes dynamical boundary conditions for the bulk field.

Boundary reflection matrices of massive ϕ 1,3-perturbed unitary minimal models
Journal of High Energy PhysicsWe propose explicit expressions for the boundary reflection matrices of the $${\mathcal{A}}_{m}+(r, s)$$ series of massive scattering theories, obtained by perturbing the $${\mathcal{A}}_{m}$$ unitary minimal models with (r, s) boundary conditions with ...

Holographic Entanglement Entropy in Boundary Quantum Field Theory
, 2018 We study the holographic entanglement entropy in a (d+1)-dimensional boundary quantum field theory at both the zero and finite temperature. The phase diagrams for the holographic entanglement entropy at various temperatures are obtained by solving the entangled surfaces in the different homology.
