Yuan, M. (author), Cohen, M.A. (author), Steele, G.A. (author)We study the mechanical dissipation of the fundamental mode of millimeter-sized, high quality-factor (Q) metalized silicon nitride membranes at temperatures down to 14?mK using a three-dimensional optomechanical cavity. Below 200?mK, high-Q modes of the membranes show a diverging increase of Q with decreasing temperature, reaching Q=1.27×108Q=1...journal article 2015

Kramer, E. (author), Van Dorp, J. (author), Van Leeuwen, R. (author), Venstra, W.J. (author)We investigate the effect of mechanical strain on the dynamics of thin MoS2 nanodrum resonators. Using a piezoelectric crystal, compressive and tensile biaxial strain is induced in initially flat and buckled devices. In the flat device, we observe a remarkable strain-dependence of the resonance line width, while the change in the resonance...journal article 2015

Bruno, A. (author), De Lange, G. (author), Asaad, S. (author), Van der Enden, K.L. (author), Langford, N.K. (author), DiCarlo, L. (author)We present microwave-frequency NbTiN resonators on silicon, systematically achieving internal quality factors above 1?M in the quantum regime. We use two techniques to reduce losses associated with two-level systems: an additional substrate surface treatment prior to NbTiN deposition to optimize the metal-substrate interface and deep reactive...journal article 2015

Kuzmin, N.V. (author), Alkemade, P.F.A. (author), 't Hooft, G.W. (author), Elie, E.R. (author)Employing an interferometric cavity ring-down technique we study the launching, propagation and reflection of surface plasmons on a smooth gold-air interface that is intersected by two parallel, subwavelength wide slits. Inside the low-finesse optical cavity defined by these slits the surface plasmon is observed to make multiple bounces. Our...journal article 2007
