Field‐Frustrated Cooperative Distortions: Suppressing Jahn‐Teller Ordering via Microwave Annealing

open access: yesAdvanced Science, EarlyView.
Microwave annealing decouples local Jahn‐Teller distortions from long‐range cooperative ordering in CuFe2O4, stabilizing a metastable cubic phase that remains locally distorted yet globally symmetry‐frustrated. Synchrotron XRD, PDF, XPS, and in situ thermal cycling reveal how non‐equilibrium MW‐phonon interactions suppress cooperative orbital‐lattice ...

Silicon/quartz bonding and quartz deep RIE for the fabrication of quartz resonator structures

2008 3rd IEEE International Conference on Nano/Micro Engineered and Molecular Systems, 2008
In this paper, silicon/quartz bonding and quartz deep RIE (DRIE) processes have been developed to fabricate micromechanical quartz resonator structures. A low temperature (< 300degC), plasma-assisted silicon/quartz bonding condition that can provide the maximum bonding shear strength of 10 MPa has been experimentally constructed.
