Content
In this course in MSc Applied Physics, we will discuss the properties of plasmonic materials in the context of nanophotonics and nanoelectronics. The basis of light interactions with metals will be discussed from where surface plasmon polaritons (SPP) will be introduced.  Various methods of SPP excitation (optical and electrical excitation) and out coupling, and imaging methods to characterize SPP will be discussed.  Next, localized surface plasmons will be introduced, including the concept of field enhancement from plasmonic coupling between multiple nanostructures. We will also cover the basic chemistry involved with nanoparticle synthesis and fabrication. We will discuss manipulation of plasmons and give an overview of plasmon propagation,  plasmonic waveguiding, plasmonic focusing, and plasmonic modes in (nano)gaps. Then we will move towards applications and discuss radiation through apertures (diffraction) and extra-ordinary transmission, followed by enhancements of emissive processes which is particularly important in sensing with emphasis SERS and refractive index sensing. After an overview of the basics of quantum mechanical tunneling junctions, the various types of (molecular) tunnel junctions will be introduced and how geometry, size and shape go hand-in-hand with their plasmonic and electronic properties. Next, we discuss in detail how such structures are used for various applications including single-molecule sensing or catalysis via plasmonic hot electron generation.

Assessment description

Assessment consists of three items: homework/assignment (“Opdracht(en)” and “Tussentijdse toetsen”, 60%), practical and report (“Practicum”, 25%), and presentation (“Presentatie”, 15%).
In the homework, students are given 2 rounds for marking. In round 1, students may fail in some answers, but they are encouraged to schedule Q&A meeting with lecturers, to discuss and improve answers for round 2. A grade of 5.5 is required from homework to enter the practical and presentation. The practical and presentations thus have to be scheduled at the end of the course.     
In the practical, students will get training to make plasmonic structures, and measure the images/spectra. In the presentations, students choose one research paper relevant to the course’s subject (plasmonic cavities, plasmonic catalysis, SERS, or plasmonic junctions) to present and critically assess it.
