dc.description.abstract |
We report on germanium coated silicon nanowires structures synthesized with metal assisted chemical etching and qualify their functionality as human respiratory sensor. The
sensors were made from p-type single-crystalline (100) silicon wafers using a silver catalyzed top-down etching, afterwards coated by 50 nm germanium thin layer using a magnetron
sputtering. The germanium post-treatment was performed by
rapid thermal annealing at 450 and 700◦C. The sensors were
characterized by X-ray diffraction diffractogram and scanning
electron microscopy. It is demonstrated that the sensors are
highly sensitive as human breath detectors, with rapid response
and frequency detectability. They are also shown to be a good
candidate for human respiratory disease diagnoses. |
