Discussion of the master's thesis of the student " Teeba Abdul Latif Ibrahim "

The public discussion took place for the master’s student (Teeba Abdul Latif Ibrahim) Department of Physics- College of Science - University of Anbar on Tuesday, September 2, 2025, in Ibn Sina Hall. for his tagged thesis

" Improving the Performance of V2O5/PANI Using Hydrothermal Method Towards Photodetectors Applications"

The discussion committee consisted of:

University of Anbar - College of Sciences - President	Prof. Dr. Ismat Ramzi Abdul Ghafour
University of Anbar - College of Sciences - Member	Prof. Dr. Mohammed Ghazi Hamad
University of Karkh - College of Energy and Environmental Sciences- Member	Assist. Prof. Dr. Ethar Yahya Saleh
University of Anbar - College of Sciences - member and supervisor	Prof. Dr. Ahmed Salman Obaid
University of Anbar - College of Sciences - member and supervisor	Prof. Dr. Ibrahim Jalil Ibrahim

This study aims to develop high-performance hybrid photodetectors based on V2O5/PANI nanocomposites synthesized via a hydrothermal method. The effects of composition ratio, reaction time, and synthesis temperature were systematically investigated. The V2O5: PANI (1:3) device prepared at 180 °C for 6 h exhibited the best performance, achieving a responsivity of 0.34 A/W, detectivity of 1.6×10²? Jones, and an external quantum efficiency of 137.5%. The superior behavior is attributed to effective band alignment, reduced defect states, and enhanced charge separation, highlighting its potential for advanced optoelectronic photodetection applications.
