Surface morphology-driven gas sensing performance of CdS-modified TiO 2 thick film: a study based on fractal concepts
Ankit Kumar Vishwakarma, Ajaya Kumar Sharma, Ram Pratap Yadav, Pradip Kumar Priya, Madhvi Yadav, Lallan YadavaCdS-modified TiO 2 thick films were analysed using AFM fractal parameters and evaluated for acetone sensing at 5000 ppm. The 2 wt% CdS–TiO 2 sensor achieved a 71% response, highlighting the role of surface morphology in gas-sensing performance.
