DEVICES INCLUDING A NEAR FIELD TRANSDUCER (NFT) WITH NANOPARTICLES

摘要

Devices that include a near field transducer (NFT) including a crystalline plasmonic material having crystal grains and grain boundaries; and nanoparticles disposed in the crystal grains, on the grain boundaries, or some combination thereof, wherein the nanoparticles are oxides of, lanthanum (La), barium (Ba), strontium (Sr), erbium (Er), hafnium (Hf), germanium (Ge), or combinations thereof; nitrides of zirconium (Zr), niobium (Nb), or combinations thereof; or carbides of silicon (Si), aluminum (Al), boron (B), zirconium (Zr), tungsten (W), titanium (Ti), niobium (Nb), or combinations thereof.
