Photopyroelectric (PPE) spectroscopy is a useful tool for examining optical properties in semiconductor materials. The ceramic (ZnO - xTiO₂) was sintered at 1270⁰C for 1 and 3 hours to investigate the variations of energy band-gap with respect to mol % of dopant TiO₂. The X-ray diffractrometry shows...
