Welcome to the Website of the Institute for Nanoelectronics
The Institute for Nanoelectronics has over the years worked on a wide range of topics in the field of nanotechnology and nanoelectronics. At an experimental level, the two main fields of activity have been nanofabrication and organic electronics. At the very beginning we bought two key equipment, namely a nanoimprinter and a glove box. Around them, over the years, the labs grew with nanocharacterization facilities, optelectronic measuring set-ups and fabrication equipment (last of which is an industrial spray coater). In parallel we have been carrying out extensive simulation and design work at device, circuit and architectural level.
Our research focuses on semiconductor nanostructures for novel applications in molecular electronics and biosensing. We develop new contact schemes for the integration of molecular devices into current semiconductor technology. This involves both, advanced patterning techniques for the sub-10 nm range as well as the electronic investigation of molecule-semiconductor interfaces. In the field of label-free detection of biomolecular interactions our present work concentrates on bio-functionalized nanowire field effect sensors and nanopore cavity devices.
Nanotechnology encompasses the understanding of the fundamental physics, chemistry, biology and technology of nanometre-scale objects. There is a tremendous interest in being able to master electronic, optoelectronic and photovoltaic effects at the nanoscale, considering that nanostructuring is the key to overcome standard limitations in device performance. Understanding how light is absorbed, charge is transported and energy is stored in such small systems is therefore a great challenge where numerical simulations play a fundamental role.
Simulation of nanoscale systems pose two important challenges: the physics is ruled by quantum mechanics and we must abandon quasi-equilibrium thermodynamic assumptions. The simulation of nanodevices is complicated by the fact that the physics of the device usually embraces effects at different length scales, from nano to meso scale. This requires multiscale approaches to describe the entire system while keeping the computational cost at a reasonable level. Our work is focused in applying and developing numerical schemes in order to simulate nanostructured devices for electronic and energy harvesting applications.
Our research focuses on theoretical and computational photonics. As a key technology covering all technical applications of electromagnetic radiation from ultraviolet over the visible to the infrared and terahertz spectral range, photonics has a major impact on many technological and economic fields. In close collaboration with experimental groups, we model photonic devices and optical systems for various applications such as metrology and sensing, biomedical imaging, photovoltaics, and optical communications. Photonics is an inherently interdisciplinary field with strong links to other areas such as nanotechnology, which becomes more and more important for modern photonic devices and structures. Furthermore, computational engineering plays a significant role in our research, involving the development and application of computational models to solve the complex physical problems arising in photonics.
