High temperature characteristics of langasite surface acoustic wave (SAW) devices coated with an AlN thin film have been investigated in this work. The AlN films were deposited on the prepared SAW devices by mid-frequency magnetron sputtering. The SAW devices coated with AlN films were measured from room temperature to 600 °C. The results show that the SAW devices can work up to 600 °C. The AlN...

For the D = 5 Majorana neutrino mass operator to have a see-saw ultraviolet completion that is viable up to the Planck scale, the see-saw scale is bounded above due to triviality limits on the see-saw couplings. For supersymmetric see-saw models, with realistic neutrino mass textures, we compare constraints on the see-saw scale from triviality bounds, with those arising from experimental limits...

The impact of ambient humidity on a surface acoustic wave (SAW) propagation in the structure consisting of hematoporphyrin (Hp) film deposited on a piezoelectric lithium niobate substrate has been studied. The SAW transmission dependencies on frequency were measured using an RF network analyzer, and the variation in the SAW velocity was measured using SAW delay-line oscillator technique. The in...
