Lanthanum calcium manganate crystals have transition temperature that tends to increase at high doses of electron irradiation, which in turn stimulates persistence of magnetic polarons up to higher temperatures.
Copper indium gallide selenide is an I-III-VI semicondutor material composed of selenium, gallium, indium and copper. It is a tetrahedrally bonded semiconductor largely found in chalcopyrite mineral.
Copper zinc tin sulfide is a quaternary semiconducting compound that has favorable optical and electronic properties similar to copper indium gallium selenide. It can be obtained from chalcopyrite structure by substituting the trivalent In/Ga with a bivalent Zn and IV-valent Sn.
Silver gallium sulfide has high short wavelength transparency edging at 550nm, excellent bulk quality across the transmission range, except for residual e-ray absorption centered at 1.8µm. Surface absorption of silver gallium sulfide may increase with time.
A unique, honeycomb-like version of the wonder material graphene could become a viable replacement for expensive platinum in dye-sensitized solar cells.

Copper (II) oxide is a higher oxide of copper and belongs to the monoclinic crystal system. It occurs as a black solid with an ionic structure that melts above 1200°C with some loss of oxygen.
Gallium selenide is a chemical compound having a hexagonal layer structure similar to that of gallium sulfide. It readily reacts with acids. Gallium selenide crystals are widely being used in photoconductor and non-linear optical material.
Copper indium gallide selenide (CIGS) is an I-III-VI semiconductor material composed of selenium, gallium, indium and copper. It is a tetrahedrally bonded semiconductor largely found in chalcopyrite mineral.
Chromium bromide is a water soluble, highly crystalline inorganic compound with the formula CrBr3. It is used in catalysts to polymerize olefins. Ultra-high purity and ultra-high compositions have good optical quality and are very useful.
