Wavelength-selective bipolar photoresponse in CVD-grown β-Bi 2 O 3 flakes for multi-logic functionality
Sourav Dey, Sirsendu Ghosal, Abdul Kaium Mia, Subhankar Debnath, Md Saifuddin, Md Tarik Hossain, P. K. GiriWe report wavelength-selective bipolar photoresponse in CVD-grown β-Bi 2 O 3 flakes and exploit it for multi-logic functions. The response arises from defect states, electron–phonon interaction, and lattice anharmonicity.
