DFT methods in combination with NMR spectroscopy are used to investigate possible variants of the mol. structure of the ion pairs of the ionic liq. (IL) 1-ethyl-3-methylimidazolium tetrafluoroborate, [EMIM][BF4], in dichloromethane. According to the comput ...
A shear mode resonator based on bulk waves trapped in c-axis oriented AlN thin films was fabricated, simulated, and tested. The active 1.55 mu m thick AlN layer was deposited on top of an acoustic Bragg reflector composed of SiO2/AlN lambda/4 layer pairs. ...
