摘要:
The invention relates to a method for generating single-crystalline aluminium nitride doped with scandium and/or yttrium, with scandium and/or yttrium contents of between 0.01 and 50 at.% with respect to 100 at.% of the total amount of substance of the doped aluminium nitride, characterized in that, in a crucible, in the presence of a gas selected from nitrogen or noble gas or a mixture of nitrogen and noble gas, a doping material selected from scandium, yttrium, scandium nitride or yttrium nitride or a mixture thereof and a source material of aluminium nitride are sublimated and recondensed on a seed material which is selected from aluminium nitride or aluminium nitride doped with scandium and/or yttrium. The invention likewise relates to a corresponding device, and the corresponding single-crystalline products and the use thereof, creating the basis for novel components based on layers or stacks of layers of aluminium gallium nitride, indium aluminium nitride or indium aluminium gallium nitride.
摘要:
Highly textured [111] oriented films such as MgO crystalline films are deposited by e-beam evaporation on ordinary soda-lime glass. Semiconductor films such as silicon can be deposited on these MgO films using eutectics at temperatures below the softening point of ordinary glass and having extremely high textured and strong [111] orientation. The invention may be used for efficient and cost effective solar cells, displays, etc.
摘要:
A method for depositing a magnesium oxide thin film on a substrate by a laser abrasion method using a sintered body or single crystal of magnesium oxide as a target. In this method, a flat processed film made of magnesium oxide having a (111) plane as its front surface is prepared, using a substrate made of strontium titanate having a (111) plane as its principal surface or yttria-stabilized zirconia having a (111) plane as its principal surface, by directly depositing a film on the principal surface of the substrate and epitaxially growing the film.

Provided is a substrate for epitaxial growth, which enables the improvement in quality of a Ga-containing oxide layer that is formed on a ²-Ga 2 O 3 single-crystal substrate. A substrate (1) for epitaxial growth comprises ²-Ga 2 O 3 single crystals, wherein face (010) of the single crystals or a face that is inclined at an angle equal to or smaller than 37.5° with respect to the face (010) is the major face. A crystal laminate structure (2) comprises: the substrate (1) for epitaxial growth; and epitaxial crystals (20) which are formed on the major face (10) of the substrate (1) for epitaxial growth and each of which comprises a Ga-containing oxide.

摘要:
Dislocation pile-ups in compositionally graded semiconductor layers are reduced or eliminated, thereby leading to increased semiconductor device yield and manufacturability. This is accomplished by introducing a semiconductor layer having a plurality of threading dislocations distributed substantially uniformly across its surface as a starting layer and/or at least one intermediate layer during growth and relaxation of the compositionally graded layer. The semiconductor layer may include a seed layer disposed proximal to the surface of the semiconductor layer and having the threading dislocations uniformly distributed therein.
