Interface Losses In Multimaterial Resonators
Luis Guillermo Villanueva Torrijo, Tom Larsen
We present an extensive study shedding light on the role of surface and bulk losses in micromechanical resonators. We fabricate thin silicon nitride membranes of different sizes and we coat them with different thicknesses of metal. We later characterize th ...

2014Passive phase noise cancellation element
Luis Guillermo Villanueva Torrijo
A passive electro-mechanical device that reduces phase noise in oscillators, thereby improving their frequency precision. The noise reduction device can consist of a pair of coupled nonlinear resonators that are driven parametrically-by modulating their na ...

Luis Guillermo Villanueva Torrijo
Synchronization of oscillators based on anharmonic nanoelectromechanical resonators. Experimental implimentation allows for unprecedented observation and control of parameters governing the dynamics of synchronization. Close quantitative agreement is found ...
2014Resistless Fabrication of Nanoimprint Lithography (NIL) Stamps Using Nano-Stencil Lithography
Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Andreea Veronica Savu, Cristina Martin Olmos, Oscar Vazquez Mena, Katrin Sidler Arnet
In order to keep up with the advances in nano-fabrication, alternative, cost-efficient lithography techniques need to be implemented. Two of the most promising are nanoimprint lithography (NIL) and stencil lithography. We explore here the possibility of fa ...

Luis Guillermo Villanueva Torrijo
Understanding and controlling nonlinear coupling between vibrational modes is critical for the development of advanced nanomechanical devices; it has important implications for applications ranging from quantitative sensing to fundamental research. However ...
2013Nonlinearity in nanomechanical cantilevers
Luis Guillermo Villanueva Torrijo
Euler-Bernoulli beam theory is widely used to successfully predict the linear dynamics of micro-and nanocantilever beams. However, its capacity to characterize the nonlinear dynamics of these devices has not yet been rigorously assessed, despite its use in ...
