| titleOfInvention | Mould for growing large-size gallium oxide crystal by guided mode method |
| abstract | The utility model discloses a die for growing large-size gallium oxide crystals by a guide die method. And in the width direction of the die, the top end of the die is a curved surface which is a concave curved surface and is an isothermal or approximately isothermal curved surface. The utility model discloses according to the thermal field distribution condition of jumbo size gallium oxide crystal, designed the mould top structure of curved surface, the camber of curved surface is carried out the design of fitting by temperature gradient distribution and is obtained. The curved surface top end structure can realize the controllable adjustment of the radial temperature gradient of the die, effectively solves the problem of growth defects caused by temperature difference when growing large-size gallium oxide crystals, can effectively reduce the growth difficulty caused by temperature difference particularly when the size is more than 4 inches, and obviously improves the quality of the crystals. Just the utility model discloses a mould is applicable in multiple die-guiding method seeding mode, can reduce the production of all kinds of defects to improve the availability ratio of crystal. |
