The outstanding charge transport properties of graphene enable numerous electronic applications of this remarkable material, many of which are expected to operate at ultrahigh, terahertz (THz) rates. In many of these applications, charge carriers in graphene are therefore exposed to very short field transients. Here we show that these THz transients do not only induce charge transport – i.e....
Small molecule identification is a core challenge in various areas of (bio)analytical science, including metabolomics and drug development. We present several examples demonstrating the direct applicability of infrared (IR) ion spectroscopy in the fields of drug metabolism and metabolomics. We present developments that combine separation by high performance liquid chromatography with IR...
Combining multiple atomic-scale layers of polar crystals allows for active modification of phonon frequencies, lifetimes, and hence engineering of the dielectric response. Specifically, new hybrid optical phonon modes emerge in these so-called crystalline hybrids (XHs) due to the modification of chemical bonds at the interfaces and confinement effects.
In our experiments, we study the...
