2021 46th International Conference on Infrared, Millimeter and Terahertz Waves (IRMMW-THz).
We present n-doped germanium-on-silicon (Ge-on- Si) antennas fabricated with CMOS mainstream methods, showing resonances between 0.1 and 0.7 THz for sensing applications. After surface functionalization with α-lipoic acid, a red-shift of the antenna

Label-free optical detection of biomolecules is currently limited by a lack of specificity rather than sensitivity. To exploit the much more characteristic refractive index dispersion in the mid-infrared (IR) regime, we have engineered three-dimensio

Here, we present 3D solutions of Maxwell’s equations using the finite element method (FEM) for sub-wavelength plasmonic THz antennas in array configurations. We show that mutual coupling between neighboring antennas causes the arrays spectral respo

While the Ge(0 0 1) surface has been extensively studied, it is still debated whether it is of conducting or semiconducting nature at room temperature. The evidence collected by angle-resolved photoelectron spectroscopy experiments in the past has le

Defects play an important role for surface reconstructions and therefore also influence the substrate growth. In this work we present a first principle calculation for the Ge(001) surface without and with tin impurities incorporated into the top surf

The growth of multi-layer germanium-tin (GeSn) quantum wells offers an intriguing pathway towards the integration of lasers in a CMOS platform. An important step in growing high quality quantum well interfaces is the formation of an initial wetting l

Carbon. 121:10-16
A combination of surface science techniques (STM, XPS, ARPES) and density-functional theory calculations was used to study the decoupling of graphene from Ni(111) by oxygen intercalation. The formation of an antiferromagnetic (AFM) NiO layer at the i
