| 摘要 |
The present invention relates to:
- transparent glass-ceramic materials which contain a spinel solid solution as the main crystalline phase and which are free of As 2 O 3 and Sb 2 O 3 ,
- corresponding precursor alumino-silicate glasses,
- articles made of said transparent glass-ceramic materials as well as a method for manufacturing such articles, and
- structures comprising a sheet made of such glass-ceramic materials and electronic or optoelectronic devices comprising such structures. Some materials of the invention are excellent substrates for high temperature growth of high quality monocrystalline or polycrystalline silicon thin films. Structures including such substrates with such thin films thereon can be used in photovoltaic devices, flat panel devices and liquid crystal devices. |
