    Sensor based on a non-ideal heterojunction to indicate X-ray images
    (2004) Smyntyna, Valentyn A.; Borschak, V. A.; Kutalova, Mariia I.; Zatovskaya, N. P.; Balaban, Andrii P.; Куталова, Марія Іванівна; Куталова, Мария Ивановна
    The sensor of optical image on the basis of non-ideal heterojunctions are investigated in detail.In this work,the opportunity to obtain the image in X-rays was investigated. It is established that investigated sensor is sensitive to soft X-ray radiation.Memory and accumulation of a signal at a room temperature,which is characteristic of the sensor at registration of images in visible light,take place for the images obtained in X-ray range,too,which makes it possible to apply such sensor in medicine and crystallography.

    The photoelectric properties of CdS crystals with combined doping are considered. The relaxation of the photocurrent determined by the long-term (months) redistribution of the sensitive impurity is found. The possibility of creating a new type of light sensors with super long memory. The medium-time (minutes) and fast (seconds) relaxation of the photocurrent under excitation by natural and infrared light are studied.

    The study of homogeneous and heterogeneous sensitized crystals of cadmium sulfide. Part IV. Features of the reverse photoexcitation method
    (Одеський національний університет імені І. І. Мечникова, 2020) Kulikov, S. S.; Куліков, С. С.; Куликов, С. С.; Borshchak, Vitalii A.; Борщак, Віталій Анатолійович; Борщак, Виталий Анатольевич; Zatovskaya, N. P.; Затовська, Наталія Петрівна; Затовская, Наталия Петровна; Kutalova, Mariia I.; Куталова, Марія Іванівна; Куталова, Мария Ивановна; Karakis, Yurii M.; Каракіс, Юрій Миколайович; Каракис, Юрий Николаевич
    For the first time, a reverse method of studying the spectral distribution curves of the photocurrent was applied, which allows to separate the contribution of equilibrium and nonequilibrium carriers. This publication is a continuation of the reviews [1-3]. In order to preserve the generality of the work, the numbering of sections is selected to be general. Numbers of formulas and figures are presented in sections. References to literature in each review are given individually. Cadmium sulfide crystals are used in our research as a convenient model material. The results obtained on them and the constructed models are also applied to other semiconductor substances.
