Semiconductor materials and devices for medical and environmental applications

Several materials used for the fabrication of semiconductor devices possess electrical, chemical, mechanical, magnetic, thermal, and physical properties in general that can be used for applications far beyond regular electron devices. In this work I introduce various materials and devices that are used as medical, agricultural, or environmental instrumentation that serves the purpose of helping humanity. This is the case of pH sensors for water quality and food production applications, or atomic-size thin layers and plasmonic devices for COVID-19 and biological applications.
