Yb-doped and Yb–Mg codoped LiNbO3 single crystals

Lithium niobate (LiNbO3, LN) is one of the most well known multifunctional materials, due to its excellent piezo-, ferro-, and pyro-electric, electro-optical, photorefractive as well as non-linear optical (NLO) properties. As a consequence, it is extensively applied in fabricating surface acoustic ...

QUARTZ CRYSTAL, THE TIMING MATERIAL

QUARTZ CRYSTAL, THE TIMING MATERIAL 1. Introduction Quartz is a piezoelectric material. A thin wafer of quartz, with electrodes attached to opposing surfaces, vibrates mechanically when voltage is applied to the two electrodes. Frequency of vibration is primarily a function of wafer dimensions. The ...
