AFM topographical analysis and an electrical transport measurement with UV exposure. (a–c) AFM image of the pristine BP, after a 2 min UV exposure and a 4 min UV exposure respectively. The roughness has increased manifold with an increase in the UV exposure. However, some points show thinning, which can be attributed to the formation of the HxPOy. (d) The Ids-Vg curve of the pristine and the UV exposed BP. (e) The decreasing trend in mobility vs exposure time.
