Optical properties of a Cr/4H-SiC photodetector in the spectral range from ultraviolet to extreme ultraviolet.

This work examines the electrical and radiometric characteristics of a photodiode based on a 4H-SiC semiconductor material with a semitransparent Cr Schottky barrier of about 7 nm thickness. The device had a photosensitive area 10 mm in diameter. The spectral responsivity was determined in the wavelength range from 40 nm to 400 nm, thus particularly extending the characterization into the vacuum- and extreme ultraviolet spectral ranges.

Autotransplantation of cryopreserved ovarian tissue--effective method of fertility preservation in cancer patients.

Objective: To review the literature and to present the latest advances in the autotransplantation of cryopreserved ovarian tissue.

Materials And Methods: A literature review was conducted for all relevant articles assessing the fertility preservation, ovarian tissue transplantation, standard freezing and vitrification of ovarian tissue.

Results: One of the promising and effective methods for fertility preservation may be the autotransplantation of cryopreserved ovarian tissue.
