研究目的
To analyze the energy loss channels for a fast electron traversing a monolayer phosphorene under oblique incidence, taking retardation effects into account, and to render the electromagnetic properties of phosphorene for photonics/plasmonics applications.
研究成果
The analysis reveals distinct energy loss behaviors in phosphorene across different frequency regimes, with anisotropic and hyperbolic responses influencing ohmic and radiative losses, highlighting its potential for photonics and plasmonics applications.
研究不足
The study is purely theoretical and does not involve experimental validation; it relies on simplified models for phosphorene conductivity and assumes vacuum conditions, which may not capture all real-world complexities.
1：Experimental Design and Method Selection:
The study employs a theoretical framework based on relativistic treatment and electromagnetic field theory, using Fourier transforms and dyadic Green's functions to model the interaction.
2：Sample Selection and Data Sources:
A monolayer phosphorene sheet is considered, with parameters derived from phenomenological models in referenced literature.
3：List of Experimental Equipment and Materials:
No specific equipment or materials are mentioned, as it is a theoretical study.
4：Experimental Procedures and Operational Workflow:
The methodology involves calculating electric fields from current densities, solving for induced fields, and computing energy loss probabilities and radiative distributions.
5：Data Analysis Methods:
Analytical calculations are performed to derive probability densities for ohmic loss and spectral angular distributions for radiative loss.
