The Role of Ultra‐Thin Buffer Layers for Achieving Ultra‐Low Dark Currents in Single‐Component Organic Photodetectors

Advanced Functional Materials, EarlyView.
Here, SubNc single‐component organic photodiodes (SC‐OPDs) are investigated, which achieve highly competitive performance metrics, including high EQE, ultra‐low JD, and high specific detectivity (D*). This study emphasizes the critical role of an organic buffer layer in studying the interface energetics and effects to achieve state‐of‐the‐art ...

Free-Electron Lasers

2014
Free electron lasers are electron beam-based sources of coherent, high-power tunable radiation which can, in principle, be designed to operate at any wavelength ranging from mm waves to X-rays. In recent years, these devices have successfully been operated at THz and hard X-ray wavelengths where conventional sources of radiation are either not ...

ac Free-Electron Laser

Physical Review Letters, 1986
A possible new source of tunable coherent radiation is analyzed. By the passing of a relativistic electron beam (relativistic factor ..gamma../sub 0/) through a homogeneous transverse ac electric or magnetic field of frequency f/sub 0/, electromagnetic radiation of frequency f--2..gamma../sub 0//sup 2/f/sub 0/ is generated by its coupling the negative ...

Electrostatic free-electron laser

Physical Review A, 1987
A new kind of free-electron-laser (FEL) scheme is proposed, that is, an FEL with an electrostatic centrifugal system of coaxial waveguide, called an ''electrostatic FEL'' for short. An annular relativistic electron beam in the laboratory frame is assumed to encounter a pump wave of TE mode.

Free Electron Lasers

Physics Bulletin, 1980
A free electron laser is a source of coherent radiation having the highly desirable characteristics of tunability over a broad range of wavelengths, efficient operation and high power output. In the ultraviolet, such a source could be used for the study of molecular and biological systems, while infrared applications may include the spectroscopy of ...
