ball milling of lithium niobate

  • Potassium Niobate Scientific

    Abstract Porous potassium niobate (KNbO 3 KN) system ceramics were prepared by a conventional sintering method using carbon black (CB) nanoparticles. First KN nanoparticles with a size of 100 nm was mixed with CB nanoparticles and binder using ball milling with ethanol. The mixture was dried and pressed into pellets using uniaxial pressing.

  • Rib Microring Resonators in Lithium Niobate on Insulator

    Abstract Rib microring resonators were fabricated via electron beam lithography and ion milling in lithium niobate on insulator (LNOI). LNOI is a single crystalline thin film of lithium niobate (LiNbO 3) bonded to 1.8 μm of SiO 2 and an LiNbO 3 substrate. Measurement results show a Q-factor of 2800 as well as a modulation depth of 18.7 dB.

    We report on two novel ways for patterning lithium niobate (LN) at submicronic scale by means of focused ion beam (FIB) bombardment. The first method consists of direct FIB milling on LiNbO 3 and the second one is a combination of FIB milling on a deposited metallic layer and subsequent RIE (Reactive Ion Etching) etching. FIB images show in both cases homogeneous structures with well
