10 nm deep, sub-nanoliter fluidic nanochannels on germanium for attenuated total reflection infrared (ATR-IR) spectroscopy
Sriram, K.K.; Nayak, Simantini; Pengel, Stefanie; Chou, Chia-Fu; Erbe, Andreas (Journal article; Peer reviewed, 2017)The fabrication of sub-nanoliter fluidic channels is demonstrated, with merely 10 nm depth on germanium, using conventional semiconductor device fabrication methods and a polymer assisted room-temperature sealing method. ... -
How to probe structure, kinetics and dynamics at complex interfaces in situ and operando by optical spectroscopy
Erbe, Andreas; Nayak, Simantini; Chen, Ying-Hsuan; Niu, Fang; Pander, Marc; Tecklenburg, Stefanie; Toparli, Cigdem (Chapter, 2017)Techniques using light in a large spectral range are well suited to study interfaces. Photon-based techniques have a special strength when it comes to application in situ and operando. This article introduces some of the ... -
Mechanism of the potential-triggered surface transformation of germanium in acidic medium studied by ATR-IR spectroscopy
Nayak, Simantini; Erbe, Andreas (Journal article; Peer reviewed, 2016)In acidic solution, germanium surfaces undergo a transformation to hydrogen-terminated surfaces at sufficiently negative electrode potentials. Herein, we used in situ and operando attenuated total reflection infrared ... -
Superoxide intermediate in the oxygen reduction on a zinc hydroxide model corrosion product
Nayak, Simantini; Biedermann, Paul Ulrich; Erbe, Andreas (Peer reviewed; Journal article, 2022)The inhibition of the electrochemical oxygen reduction reaction (ORR) by zinc corrosion products plays an important role in the corrosion protection of galvanized steel. Hence, the electrocatalytic mechanism of the ORR on ... -
Vibrational spectroscopic study of pH dependent solvation at an Ge(100)-water interface during an electrode potential triggered surface termination transition.
Niu, Fang; Rabe, Martin; Nayak, Simantini; Erbe, Andreas (Journal article; Peer reviewed, 2018)The charge-dependent structure of interfacial water at the n-Ge(100)-aqueous perchlorate interface was studied by controlling the electrode potential. Specifically, a joint attenuated total reflection infrared spectroscopy ...
