Applied Physics

Applied physics studies the electro-optical properties of bulk and low-dimensional materials influenced by electromagnetic fields or mechanical waves for application in a new generation of electro-optical materials used in electrical devices.

The optical and thermal properties of such materials in special environments such as resonant microcavities to exploit the extreme properties are examined.

These studies also underpin the fabrication and control of microparticles/micro specimens based on new materials for biomedical applications such as the interaction, enhancement, or destruction of a biological specimen under controlled microparticle conditions.

Research Engagements & Partners

Collaborative studies between LAP and partners are carried out based on the fair and transparent cooperation, in compliance with the laws of the host country, regulations of the host research institution, and regulations about the integrity and honesty of the international scientific community.

National and international partners work together to conduct parallel research to solve problems that cannot be solved by individual or domestic research groups.

Partners provide core research facilities, such as (super) computer systems to run simulation software, simulation-computation software, labs for prototyping, measurement, analysis, and networking to enhance the reputation of research.
