This seminar discusses advances in the fabrication and optoelectronic properties of quantum-confined solid-state materials from the two viewpoints of bottom-up (e.g. wet-chemistry or molecular beam epitaxy) vs. top-down methods. The overarching hypothesis is that these communities, which currently act largely separately due to the different chemical approaches, face many identical physical challenges in the application of these nanomaterials for optoelectronics, such that an interdisciplinary exchange holds for a high degree of synergy.

With the advent of cryptocurrency mining, the wide-spread utilization of pretrained text generators and a superlinear growth in transmitted data volume, miniaturization of components for Information and Communication Technology (ICT) is a major challenge for semiconductor physics. It is anticipated that the world-wide electricity consumption due to ICT will exceed 10% in 2025, which requires major improvements in the energy efficiency of their key components to balance the growing demand for ICT applications with its energy consumption. Nanotechnology and the fabrication of device components with spatial confinement in one, two or even three dimensions has been at the forefront of providing solutions to this challenge. The seminar will focus on transport and optics in nanomaterials, detail characterization techniques and provide insights into a theoretical understanding and modelling of nanoscalic materials. While most materials of relevance in the context are semiconductors, the seminar will also include plasmonic nanomaterials, for instance to improve semiconducting applications by electromagnetic field enhancement. The overall goal of the seminar is to unite the top-down with the bottom-up nanofabrication community to jointly develop nanotechnological solutions for a faster and more energy- efficient device physics of the future.

The conference language will be English. The Wilhelm and Else Heraeus-Foundation bears the cost of full-board accommodation for all participants.
