摘要: Abstract Gallium oxide (Ga 2 O 3) nanorods were prepared from commercial gallium nitride (GaN) powder via the simple thermal annealing method by one step, and they were characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), transmission electron microscope (TEM) and energy dispersive X-ray spectroscopy (EDS). The thick film humidity sensors were prepared by spin-coating the sensing materials on Al 2 O 3 ceramic substrates coated with Ag–Pd interdigitated electrodes and the humidity …
