The Physics Department of Shivaji University, Kolhapur organized a Guest Lecture on the topic “Fabricating Semiconductor Nanostructures for Optoelectronic and Photocatalytic Applications” on Thursday, 4th May 2023 at 8:30 a.m. The program was held in the Auditorium, Physics Department, Shivaji University, Kolhapur. The lecture aimed to expose students, research scholars, and faculty members to recent advances in semiconductor nanostructure fabrication and their growing importance in optoelectronic and photocatalytic technologies.
The distinguished speaker for the event was Prof. Umapada Pal from IFUAP, Benemérita Universidad Autónoma de Puebla, Puebla, Mexico. Prof. Pal is an internationally renowned researcher in the field of nanomaterials and semiconductor physics. The session began with a brief introduction of the guest by the organizing committee, highlighting his academic achievements, research contributions, and international collaborations. The dignitaries on the dais emphasized the importance of such interactions in fostering academic growth and global research perspectives among students.
During his lecture, Prof. Pal provided a comprehensive overview of various fabrication techniques used for developing semiconductor nanostructures, including chemical vapor deposition, sol–gel methods, hydrothermal synthesis, and physical deposition techniques. He explained how controlling size, shape, and surface properties at the nanoscale significantly influences the optical and electronic behavior of materials. The talk further elaborated on how these engineered nanostructures enhance light absorption, charge transport, and catalytic efficiency, making them highly suitable for applications such as solar cells, LEDs, photodetectors, and environmental photocatalysis.
Prof. Pal also shared insights from his own research work, presenting experimental results and case studies that demonstrated the practical performance of nanostructured materials in optoelectronic devices and pollutant degradation systems. The audience showed keen interest in understanding the challenges associated with large-scale fabrication, material stability, and cost-effective production. The interactive question-and-answer session that followed allowed participants to clarify doubts and engage in meaningful discussions about future research directions in nanotechnology.
The lecture concluded with a vote of thanks delivered by a faculty member from the Physics Department, expressing sincere gratitude to Prof. Umapada Pal for his valuable time and enlightening presentation. The event was highly informative and inspiring, leaving a lasting impression on students and researchers. The Physics Department, Shivaji University, Kolhapur reaffirmed its commitment to organizing such academic programs that promote scientific curiosity, innovation, and international collaboration.
