Nanophysics – fundamental research

Introduction

Most of the modern fundamental research in nanophysics exploits quantum physics effects, whether in quantum technologies, quantum Hall effect, 2D electron gases or other physical phenomena. All of these devices have one thing in common: The feature size of the relevant active area is extremely small and requires ultra-high resolution capabilities in the single digit nm-range, something that all RAITH charged particle optics columns can provide. Using efficient parameter switching or applying smart mix and match strategies, these functional areas need to be connected to the outside macroscopic world using specific RAITH functionality embedded in its systems.

Application

Metalenses / metamaterials

Metalenses and metamaterials represent groundbreaking innovations in optics and material science. Metalenses are ultrathin, flat (2D-) lenses composed of nanostructures, capable of manipulating light at the subwavelength scale. Unlike traditional lenses, metalenses utilize engineered surface patterns to control the phase, amplitude, and polarization of light, enabling unprecedented control over light propagation and focusing. Metamaterials, on the other hand, are artificial materials engineered to exhibit properties not found in natural substances. By designing structures smaller than the wavelength of light, metamaterials can manipulate electromagnetic waves in extraordinary ways, leading to applications such as invisibility cloaking, super-resolution imaging, and efficient energy harvesting.
