It should be noted that during corona discharge, the activation energies of the deep level (0.7 eV) change significantly depending on the potential of the corona discharge (see Figure 2 in the box). This change is due to the influence of the optical ionization energy of the deep level located in the region of the volume charge near the SiO2 layer (this is indicated by experimental results). If we assume that this change occurs due to the Pool Frenkel effect [5], then the mixing (delta-E) level can be estimated using the formula
where, is the dielectric constant of CdTe, is the charge of the electron. Then, according to our estimates, the electric field strength in the vicinity of the defect is 105 V/s, which is quite reliable.
The situation arising in a CdTe film under the action of an embedded field corresponds to the model developed for a polysilicon field effect transistor [6]. The model considered in this paper is similar to the model [6], if identified with the control electrode of a field-effect transistor. Therefore, the numerical calculations of the potential distribution in a polycrystalline semiconductor are quite applicable for the embedded charge of a CdTe film. From the calculation results, the effect of an external field on the polycrystalline structure follows that a weak field only deforms the distribution of carriers, while a strong field leads to a decrease in the value of intercrystalline barriers due to the unification of the volume of the crystallite. These results show that the built in field can lead to a decrease in the height of the barrier in the film (at U <10 V), and even to its disappearance (at U> 60 V) (on one of its surfaces), and then the remaining potential barrier becomes predominant, in the other its opposite near-surface region.
Conclusion
Summing up the analysis of the results, it is shown that the spectral photosensitivity of the CdTe layer by short circuit current and photo EMF can be controlled by the induced built in electric charge of the dielectric created by the external corona discharge potential in the CdTe (film) SiO2 (dielectric) Si (semiconductor) heterostructure.
This opens up new possibilities for the creation of semiconductor devices sensitive to electromagnetic radiation, used in optoelectronics as a photosensitive device with a spectral characteristic in a wide sensitivity range. This effect is also associated with fundamentally new capabilities of semiconductor devices with variable spectral characteristics and matching it with an emitter, which is important for robots (the visual organ of a robot, where color vision is needed), for devices and information recording systems.

Annotation. The theory of wave-particle dualism is well-known today, along with many other theories aimed at explaining various types of phenomena. However, it is worth noting that until recently, the method of explaining the phenomena of wave-particle dualism in a more visual form, which appeared from Jungs experiment, was questioned. The present study is aimed at presenting this model.
Keywords: particle-wave dualism, wave, particle-corpuscle, wave function, probability distribution, potential well, two-slit experiment.
Аннотация. Теория корпускулярно-волнового дуализма сегодня является общеизвестной, наряду с многими другими теориями, направленные на объяснение различных типов явлений. Однако, стоит отметить, что до последнего времени ставилось под вопрос метод объяснения в более наглядной форме явлений корпускулярно-волнового дуализма, появившаяся из эксперимента Юнга. На представление этой модели и направлено настоящее исследование.

The so-called two-slit experiment is widely known, in which a stream of corpuscle particles was directed, as originally assumed, towards a plate with two thin slits, and a screen was located behind it. It was logical that after directing the flow of particles, initially photons from coherent laser radiation, two bands should have been observed on the screen, but instead the so-called interference pattern was observed on the screen. It consisted of a large number of bands with different sizes and brightness, while the maximum was determined in the middle.
