NITRIDE PHOTODETECTORS IN UV BIOLOGICAL EFFECTS STUDIES

摘要

The role of the solar UV radiation in our biosphere is highlighted. Action spectra of solar UV radiation in biological processes are summarized. The erythema-weighted response has become standard for UV biological action monitoring. Fluorescence techniques and the requirements of AlInGaN-based UV detectors in biophotonics are described. AlGaN detectors fitting the erythema action spectrum are presented. QW nitride-based photodetectors, suitable for multifunctional integrated biochips, are introduced. Problem areas are discussed.
