Semiconductor Sensors

Dear Colleagues,

This special issue provides a forum for the latest research in semiconductor based sensors for gas, chemical, and bio detection, and various medical applications. It features a balance between theoretical and experimental research in basic device physics, novel materials and device structures, sensor fabrication and the transformation of research into products. The chemical sensor market represents the largest segment of the global sensor market, and semiconductor based sensors fabricated using mature micro-fabrication techniques and novel nanotechnologies are the major contestants within this sector. Silicon based sensors remain dominant due to their low cost, reproducibility, controllable electronic behaviors, and abundant data of chemical treatments on silicon oxide or glass. Wide band-gap based compound semiconductor sensors are suitable to be operated in harsh environments, for instance, high temperature, high pressure, and corrosive ambient. Nanomaterial devices so far have provided the best alternatives for fast, label-free, sensitive, selective and multiple detections for both preclinical and clinical applications. Results from Si, wide energy bandgap semiconductor devices, metal oxide and nanomaterial based sensors are particularly welcome.
