Moving liquids with light: Photoelectrowetting on semiconductors

S. Arscott

By linking semiconductor physics and wetting phenomena a brand new effect termed “photoelectrowetting-on-semiconductors” is demonstrated here for a conducting droplet resting on an insulator-semiconductor stack. Optical generation of carriers in the space-charge region of the underlying…

Magnetic field modulated dielectric relaxation behavior of Pt/BiScO3-PbTiO3/La0.7Sr0.3MnO3 heterostructure in metal-insulator transition region : an equivalent-circuit method

J.Y. Zhu, J. Yang, W. Bai, C.G. Duan, S. Zhang, G.S. Wang, X.L. Dong, Denis Remiens, X.D. Tang

Utilizing temperature and magnetic field dependent dielectric spectroscopy, two different dielectric relaxation processes, both accompanied with prominent positive magnetodielectric (MD) effects, were observed in Pt/BiScO3-PbTiO3/La0.7Sr0.3MnO3 (Pt/BSPT/LSMO) heterostructure. An equivalent circuit…

Milliwatt-level output power in the sub-terahertz range generated by photomixing in a GaAs photoconductor

Emilien Peytavit, Sylvie Lepilliet, Francis Hindle, Christophe Coinon, Tahsin Akalin, Guillaume Ducournau, Gaël Mouret, Jean-Francois Lampin

It is shown from accurate on-wafer measurement that continuous wave output powers of 1.2 mW at 50 GHz and 0.35 mW at 305 GHz can be generated by photomixing in a low temperature grown GaAs photoconductor using a metallic mirror Fabry-Pérot cavity. The output power is improved by a factor of about…
