Roles

Ali Ramadan Ahmed Khalf is one of the faculty members of the Department of Physics at the Faculty of Education-Tripoli, currently working at the University of Tripoli as a faculty member since 2010, he was assigned the task of coordinator for study and examinations in the department during the period 2012-2015 in addition to teaching many courses to students of the Department of Physics and Chemistry at the faculty.

Careers

He worked as a physical researcher at the Research and Development Center (formerly the Central Organization for Technical Research) 1990-2010 within a research team to develop an optical communication system using laser, then he worked as a faculty member at the University of Tripoli in the Department of Physics, Faculty of Education, Tripoli since 2010, during the period from 2017-2022, he was sent to prepare a doctoral degree, and since the beginning of the fall semester 22/2023, he works as a faculty member in the Department of Physics, Faculty of Education, Tripoli.

Research Interests

During the period of 1990-2010, most of the research was in the field of laser optics, where a number of optical systems were designed and implemented to control the laser beam divergence of the transmitter that uses diode lasers, as well as optical gathering systems for laser receivers. Then during the study period to prepare the doctoral degree 2017-2022, the research was in the field of nanoelectronics physics, where the research focused on organic solar cells, and the following are the participations in scientific publications and research papers published in this field:
