SAM Sputter target

In the field of thin-film technology, coating materials with low loss absorption, excellent mechanical properties, easy preparation, and stable performance have always been the materials of choice for process and designers. The lanthanum titanate film shows incomparable superior performance in this respect. Sputter coater targets are important materials for making thin films.

The lanthanum titanate crystal La2Ti2O7 belongs to the monoclinic system and has a perovskite-like structure. The space group at room temperature is P21. Lanthanum titanate crystals have good ferroelectric, photocatalytic, and electro-optical characteristics, and have a wide range of application prospects in the fields of light and electricity. It has a very high Curie temperature (1500 ℃) and a large coercive field (45kV / cm), which can be applied to high-temperature electro-optical equipment and information storage, such as high-temperature inverters, ferroelectric random access memory (FRAM), etc.

Lanthanum titanate crystals have excellent photocatalytic activity and have good application prospects in water decomposition reactions, fuel cells and other energy conversion technologies. Studies have shown that lanthanum titanate thin films have good process stability. Whether at room temperature or under heating deposition, or no matter how much oxygen is charged (or not oxygenated) during evaporation, the refractive index of the evaporation beam is not changed. And the extinction coefficient is extremely small, and the laser damage threshold is stable.

Lanthanum titanate thin film materials are used in the manufacture of optoelectronic devices, such as display technology, imaging technology, light output and light integrated devices. This material has a stable high refractive index, high homogeneity, and high transmittance. At present, lanthanum titanate crystals have been widely used as coating materials in the manufacture of high-performance photovoltaic devices. In view of the excellent properties of lanthanum titanate thin film with low loss absorption, easy preparation and stable performance, it can be used as an excellent coating material for laser thin film preparation.

Often when we hear the words "precious metal", we think first of gold, silver, and platinum. Our connotations are aesthetic, economic, and artistic. We have gold-plated connectors for audio and video, platinum components in automobile catalysts, titanium implants and prostheses in our skeletons. But there's a whole different world of precious metals as used in high technology, paving the way to fulfilling our scientific ambitions.

Probably the most well-known precious metal is Gold (Au). Since the ancient times recognized as remarkably resistant to external conditions and inspiring countless generations with its beauty and shimmer. In more recent times gold found its way into science and technology. Some of the applications include coating organic specimens and non-conducting materials to be able to view them with a scanning electron microscope. High-end CDs use gold as a reflecting layer to enhance audio quality. Gold foil is used as protective coating in satellites and many delicate electronic devices.

Iridium (Ir) is one of the rarest and most chemically inert metals found in the Earth's crust. It also has very low thermal expansion, which is why the International Prototype Meter in Sevres was made primarily from iridium. It was widely adopted in radioisotope thermoelectric generators used in many space probes and radio beacons in remote areas on Earth. It is also prominent in particle physics, where it is used to produce antiprotons.

One more example is palladium (Pd) a well-known catalyst in chemistry. It also features in multilayer ceramic capacitors, where it is used to manufacture electrodes. Palladium membranes are employed in membrane reactors to produce high purity hydrogen.

These are just a few of the manifold uses of precious metals in modern technology. Because of their purity and excellent electrochemical parameters, they will see even wider adoption in nanotechnology and new generations of computers. The already developed market for precious metal raw materials and components will have to grow to accommodate the coming wave of change. For people considering investing in that market, this might be the right time to do so.
