Introduction

Introduction


The Department of Applied Physics (AP) focuses on five research areas: (1) Energy Materials and Devices, (2) Nanomaterials, (3) Photonics, Plasmonics and Optoelectronics – Materials and Devices, (4) Smart Materials and Devices, and (5) Theoretical and Computational Physics. Through our long term drive for academic excellence, AP has achieved outstanding results, including publications in internationally renowned journals, awards by local and international institutes, patents, elected fellowships in well-recognised international academic societies, and grants from government and industrial bodies. For more information, please visit our departmental website at https://www.polyu.edu.hk/ap/.

 

Strengths of the Department

 

AP treasures our tradition of maintaining strong links with local industries and offering application-oriented curricula. Our active engagement in research and consultancy work has been recognised by both academia and industry. The research quality of our staff members and postgraduate students has also received recognition through research awards, grants, fellowships and scholarships.

 

The Research Assessment Exercise (RAE) 2014 conducted by the University Grants Committee (UGC) found that AP produced the largest amount of world-leading (4*) research work in PolyU. AP ranks 1st in the Materials Science cost centre and comes in 2nd place among all Physics Departments in Hong Kong.
