Excitation of terahertz plasmon-polariton in a grating coupled two-dimensional electron gas with a Fabry-Pérot cavity

Yongdan Huang, Hua Qin, and Baoshun Zhang et al.

Terahertz plasmon-polariton modes are excited and probed in a grating coupled GaN/AlGaN two-dimensional electron gas embedded in a Fabry-Pérot cavity using a terahertz time-domain spectroscopy at 8 K. A strong coupling between the plasmon modes and the cavity modes was observed. Electromagnetic si ... [Appl. Phys. Lett. 102, 253106 (2013)] published Thu Jun 27, 2013.

Feasibility of atomic layer etching of polymer material based on sequential O2 exposure and Ar low-pressure plasma-etching

Evelina Vogli, Dominik Metzler, and Gottlieb S. Oehrlein

We describe controlled, self-limited etching of a polystyrene polymer using a composite etching cycle consisting of sequential deposition of a thin reactive layer from precursors produced from a polymer-coated electrode within the etching chamber, modification using O2 exposure, and subsequent low ...
