Atomic Calligraphy: The Direct Writing of Nanoscale Structures using MEMS
Matthias Imboden, Han Han, Jackson Chang +4
We present a micro-electromechanical system (MEMS) based method for the resist free patterning of nano-structures. Using a focused ion beam (FIB) to customize larger MEMS machines,…
Electrostatically actuated silicon-based nanomechanical switch at room temperature
Diego N. Guerra, Matthias Imboden, Pritiraj Mohanty
We demonstrate a silicon-based high frequency nanomechanical device capable of switching controllably between two states at room temperature. The device uses a nanomechanical reson…
Evidence of universality in the dynamical response of micromechanical diamond resonators at millikelvin temperatures
Matthias Imboden, Pritiraj Mohanty
We report kelvin to millikelvin-temperature measurements of dissipation and frequency shift in megahertz-range resonators fabricated from ultra-nanocrystalline diamond. Frequency s…
High quality factor gigahertz frequencies in nanomechanical diamond resonators
Alexei Gaidarzhy, Matthias Imboden, Pritiraj Mohanty +2
We report actuation and detection of gigahertz-range resonance frequencies in nano-crystalline diamond mechanical resonators. High order transverse vibration modes are measured in…
Scaling of dissipation in megahertz-range micromechanical diamond oscillators
Matthias Imboden, Pritiraj Mohanty, Alexei Gaidarzhy +2
We report frequency and dissipation scaling laws for doubly-clamped diamond resonators. The device lengths range from 10 microns to 19 microns corresponding to frequency and qualit…
Pions versus Magnons: From QCD to Antiferromagnets and Quantum Hall Ferromagnets
O. Bar, M. Imboden, U. -J. Wiese
The low-energy dynamics of pions and magnons -- the Goldstone bosons of the strong interactions and of magnetism -- are analogous in many ways. The electroweak interactions of pion…
