Control of microstructure and composition of reactively sputtered vanadium nitride thin films based on hysteresis curves and application to microsupercapacitors

Allan Lebreton, Marie-Paule Besland, Pierre-Yves Jouan, Tatiana Signe, Cédric Mannequin, Mireille Richard-Plouet, Maryline Le Granvalet, Christophe Lethien, Thierry Brousse, Jérémy Barbé

Vanadium nitride (VN) thin films were prepared by reactive DC magnetron sputtering of a vanadium target using nitrogen as reactive gas. The structural, morphological, and compositional evolution of these films is described based on hysteresis diagrams plotting the sputtering power versus nitrogen…

Spintronic terahertz emitters with integrated metallic terahertz cavities

Martin Mičica, Adrien Wright, Pierre Koleják, Geoffrey Lezier, Kamil Postava, Jacques Hawecker, Anna de Vetter, Jérôme Tignon, Juliette Mangeney, Henri Jaffrès, Romain Lebrun, Nicolas Tiercelin, Mathias Vanwolleghem, Sukhdeep Dhillon

Spintronic terahertz emitters (STEs), based on optical excitation of nanometer thick ferromagnetic/heavy metal (FM/HM) heterojunctions, have become important sources for the generation of terahertz (THz) pulses. However, the efficiency of the optical-to-THz conversion remains limited. Although…

A G-band Packaged Amplified Noise Source using SiGe BiCMOS 55 nm Technology

Victor Fiorese, Joao Carlos Azevedo Goncalves, Simon Bouvot, Sylvie Lepilliet, Daniel Gloria, Guillaume Ducournau, Christophe Gaquière, Emmanuel Dubois

This article introduces the first BiCMOS SiGe technology based packaged noise source (NS) operating in G-band (140-220 GHz). An amplified PN junction diode has been packaged and biased in avalanche mode to generate Excess Noise Ratios (ENRav) of approximately 25 dB between 140 and 170 GHz at…
