Refractive index and extinction coefficient of thin film ...

Characterizing thin films. The refractive index (n) and extinction coefficient (k) are related to the interaction between a material and incident light, and are associated with refraction and absorption (respectively).They can be considered as the "fingerprint of the material". Thin film material coatings on various substrates provide important functionalities for the microfabrication ...

Allotropy - Wikipedia

Allotropy or allotropism (from Ancient Greek ἄλλος (allos) ''other'', and τρόπος (tropos) ''manner, form'') is the property of some chemical elements to exist in two or more different forms, in the same physical state, known as allotropes of the elements. Allotropes are different structural modifications of an element; the atoms of the element are bonded together in a different manner.

New "metalens" shifts focus without tilting or moving ...

Feb 22, 2021· Earlier this year, the researchers reported adding another element, selenium, to GST to make a new phase-changing material: GSST. When they heated the new material, its atomic structure shifted from an amorphous, random tangle of atoms to a more ordered, crystalline structure.

Thermoelectric materials with crystal-amorphicity duality ...

Apr 16, 2021· The material series (Cu1−xAgx)2(Te1−ySy), 0.16 ≤ x ≤ 0.24 and 0.16 ≤ y ≤ 0.24, adopt a complex orthorhombic structure featured by the S/Te size mismatch-induced crystal-amorphicity duality. The unique crystal structure leads to extremely low lattice thermal conductivities and high zT …

Boron - Element information, properties and uses ...

Amorphous boron is used as a rocket fuel igniter and in pyrotechnic flares. It gives the flares a distinctive green colour. The most important compounds of boron are boric (or boracic) acid, borax (sodium borate) and boric oxide.
