The work is devoted to the development of a new direction in creating of broadband photo sensors which distinctive feature is the possibility of dynamic adjustment of operating frequency range. The author's results of study of red threshold control of classic photoelectric effect were the basis for the work implementation. This effect was predicted theoretically and observed experimentally during irradiation of nanoscale carbon structure of planar-edge type by stream of low-energy photons. The variation of the accelerating voltage within a small range allows you to change photoelectric threshold for carbon in a wide range -from UV to IR. This is the consequence of the localization of electrostatic field at tip of the blade planar structure and of changes in the conditions of non-equilibrium electrons tunneling from the boundary surface of the cathode into the vacuum. The generation of nonequilibrium electrons in the carbon film thickness of 20 nm has a high speed which provides high performance of photodetector. The features of the use of nanoscale carbon structure photocurrent registration as in the prethreshold regime, and in the mode of field emission existence are discussed. The results of simulation and experimental examination of photosensor samples are given. It is shown that the observed effect is a single-photon tunneling. This in combination with the possibility of highspeed dynamic tuning determines the good perspectives for creation of new devices working in the mode of select multiple operating spectral bands for the signal recording. The architecture of such devices is expected to be significantly simpler than the conventional ones, based on the use of tunable filters.

“…In recent theoretical and experi mental investigations, satisfactory results on field elec tron emission were only obtained in the edge regions of CNT arrays [9]. The authors believe that the pros pects for the development of VCL lamps are related to the implementation of structures and the development of technologies for manufacturing cathodes of planar edge type [5,6,10] based on diamond like films. Standard equipment for 1.5 µm technology ensures the stability of processes involved in the formation of the topology of field emission structures, while also providing sufficient sensitivity to control parameters (e.g., for emitter edge formation with 20-30 nm pre cision).…”

Results of experimental and theoretical investigation of vacuum cathodoluminescent (VCL) light sources with field electron emission from carbon containing structures are presented. Comparative analysis of the distribution of current on the light emitting anode surface in VCL sources of various designs has been performed. The influence of pulsed regime parameters on the VCL source brightness and efficiency has been evaluated. Promising directions in the development of VCL light sources based on planar edge type field emission structures are discussed.
