    摘要: Zinc oxide layer, including pure zinc oxide and doped zinc oxide, can be deposited with preferred crystal orientation and improved electrical conductivity by employing a seed layer comprising a metallic element. By selecting metallic elements that can easily crystallized at low temperature on glass substrates, together with possessing preferred crystal orientations and sizes, zinc oxide layer with preferred crystal orientation and large grain size can be formed, leading to potential optimization of transparent conductive oxide layer stacks.

    摘要: A low-defect-density crystalline structure comprising a first crystalline material, a layer of second crystalline material epitaxially grown on the first crystalline material, and a layer of third crystalline material epitaxially grown on the second layer such that the second layer is positioned between the first crystalline material and the third crystalline material. The second and third crystalline materials cooperate to form a desirable relationship. The crystalline structures of the second crystalline material and third crystalline material have a higher crystalline compatibility than the first crystalline material and third crystalline material. The layer of second crystalline material is sufficiently thick to form the desirable relationship with the third crystalline material but sufficiently thin for the layer of second crystalline material to be strained. The layer of third crystalline material is grown to a thickness beyond a thickness had the third layer been grown on an unstrained second layer.

    摘要: This invention relates to reusable crucibles for production of ingots of semiconductor grade silicon made of nitride bonded silicon nitride (NBSN). The crucibles may be made by mixing silicon nitride powder with silicon powder, forming a green body of the crucible, and then heating the green body in an atmosphere containing nitrogen such that the silicon powder is nitrided forming the NBSN-crucible. Alternatively the crucibles may assembled by plate elements of NBSN-material that are to be the bottom and walls of a square cross-section crucible, and optionally sealing the joints by applying a paste comprising silicon powder and optionally silicon nitride particles, followed by a second heat treatment in a nitrogen atmosphere.
