Nanoacoustics and Nanophononics

Learnweb: NANSAMATN-2023_2

QISPOS/LSF: 114023

Lecturers: Dr. Emeline Nysten, Prof. Dr. Hubert Krenner 

Overview:

In solid state physics, mechanical excitations at the nanoscale and their quasiparticles, phonons, are ubiquitous. Very often, they are considered as a bothersome evil and limitation to the material functionalities and devices performance. Phonons however are the unsung heroes in modern information technology and are indispensable for Gigahertz signal processing. Dozens of micro- and nanoacoustic devices are found in your laptop, smartphone or WIFI router and their operation uses the unique properties of phonons for wireless communication.

In this lecture, you will learn that acoustic phonons can be harnessed to sense and manipulate the important material properties. The lecture will begin with an introduction to the basics of phonons and elastic waves in solids and then will go over their excitation, measurement and applications, both in modern technologies and recent research.

2D Materials

Learnweb: 2DM-2023_2

QISPOS/LSF: 114004

Lecturers: Prof. Dr. Ursula Wurstbauer and Prof. Dr. Hubert Krenner

Overview:

This module provides a detailed overview on a fascinating new class of solid state materials and a fast growing research area: two-dimensional (2D) materials that are truly two-dimensional solids with a thickness of about 1 nm. Within a layer there is strong covalent bonding between atoms and weak van-der Waals coupling between adjacent layers. Nevertheless, the properties of 2D solids strongly depends on the number of layers and interaction with environment/substrate. Depending on the chemical compositions, those materials exhibit fascinating properties making them very promising for electronic, opto-electronic, spin- and valleytronics applications, but also for solar and (photo-)electrochemical energy conversion and for the realization of quantum technologies.

Topical Lecture Series: Solid-state nanosystems

Learnweb: TLSSN-2023_2

QISPOS/LSF: 114024

Coordination: Prof. Dr. Hubert Krenner
Lecturers: Scientists of the Physikalische Institut

Overview:

This lecture series is a new course which is offered by groups of the Physikalische Institut to introduce to you cutting-edge research topics on solid-state nanosystems here in Münster. 

The ability to control and sense the properties of solid-state materials at the nanoscale lays the foundation for both groundbreaking fundamental discoveries and practical applications in consumer devices. Famous examples are the scanning tunnelling microscope to resolve and manipulate single atoms on surfaces or semiconductor quantum dots found in modern flatscreen displays, lasers or solar cells.

This lecture series gives a comprehensive overview on the cutting-edge research topics pursued at the Physikalische Institut ranging from scanning probe microscopy/spectroscopy of functional interfaces, emerging magnetic and topological phenomena in two-dimensional materials, spin manipulation based on exchange and spin-orbit interaction, single quantum emitters for quantum technologies to integrated circuits controlled by nano-earthquakes.

In this course you learn how emergent physical phenomena in nanoscale materials can be unraveled using high-resolution spectroscopy and harnessed for practical applications in future devices.

Here are some important information on the class which are bundled in the information sheet available for download

The course consists of two 90-minute contributions from each research group which can be complemented with lab tours.

Students in the Bachelor program are equally encouraged to attend this course to learn about opportunities for Bachelor thesis projects at the forefront of modern solid-state and quantum physics.
