Lanthanum Strontium Manganate Sputtering Targets and Applications

Lanthanum Strontium Manganate (La0.7Sr0.3MnO3) Sputtering Target (Size:1'' ,Thickness:0.250'' , Purity: 99.9%) is an oxide ceramic material with the general formula La1−xSrxMnO3, where x describes the doping level.
Lanthanum Strontium Manganate (La0.7Sr0.3MnO3) Sputtering Target has a perovskite-based crystal structure, which has the general form ABO3. In the crystal, the 'A' sites are occupied by lanthanum and strontium atoms, and the 'B' sites are occupied by the smaller manganese atoms. In other words, the material consists of lanthanum manganite with some of the lanthanum atoms substitutionally doped with strontium atoms. The strontium doping on lanthanum introduces extra holes in the valence band and thus increases electronic conductivity.
This material is commonly used as a cathode material in commercially produced solid oxide fuel cells because it has a high electrical conductivity at higher temperatures. Also, Lanthanum Strontium Manganate cathodes used in solid oxide fuel cells have exhibited enhanced catalytic activity after polarization.
Now let’s see that solid oxide fuel cells and how Lanthanum Strontium Manganate (La0.7Sr0.3MnO3) Sputtering Target is used in this area. Solid oxide fuel cells offer an efficient means to convert chemical energy to electricity, with potential applications in transportation, distributed generation, remote power, defense, and many others. An individual solid oxide fuel cell is composed of a fully dense solid electrolyte, a porous cathode or air electrode, and a porous anode or fuel electrode. Fuel cell stacks consist of individual cells that are joined by electrical interconnect plates, and operate in the temperature range of 700–1000 oC. Below you may see the schematic of solid oxide fuel cell with associated reactions. In this system lanthanum strontium manganate most often serves as anode.

Rundown about Silicon Oxide Wafer

The main insulating material used in micro-technology is Silicon Dioxide, which in chemical symbols is written as SiO2. In semiconductor technology, SiO2 thin film layers are mainly used as dielectric material film in transistors, capacitors (DRAM) or flash-memories. Silicon Oxide Wafers are produced using crystallization, solid state and other ultra-high purification processes such as sublimation. This process forms a cylindrical ingot, which is then sliced and polished to form wafers. Thermal oxide is a kind of "grown" oxide layer, compared to CVD deposited oxide layer, it has a higher uniformity, and higher dielectric strength, it is an excellent dielectric layer as an insulator . In most silicon- based devices, thermal oxide layer play an important role to pacify the silicon surface to act as doping barriers and as surface dielectrics. The simplest way to produce an insulating silicon oxide layers (SiO2) on silicon wafers is to oxidize silicon with oxygen, which ...

New Way of Deaf-Mute Communication with 3D Graphene

Image retrieved from: http://blogs.rsc.org/cc/2016/09/01/3d-graphene-adds-dimension-to-deaf%E2%80%93mute-communication/ Chinese scientists have developed wearable electronic device with conductive 3D graphene structure to translate sign language into written text. This technology can be applied by injecting graphene ink from a syringe under printed electronic field. For medical field, such as adhesive patches which determine heart, brain signal and neural activity, wearable and bio-integrated medical devices are very important. Due to noticeable properties of cast graphene, for example a 2D honeycomb lattice, excellent mechanical and electrical behaviors, Graphene has an important material in warble technology. However, it is difficult to preserve advantages of Graphene material in a 3D material which has an information about forces from every angle. Yanlin Song  and co-workers at the University of the Chinese Academy of Sciences, Beijing, and Shenyang Jianzhu University...
