In particular, materials with very different lattice constants or different crystal phases ( wurtzite or zincblende in this case ) are difficult to combine.
32.
The presence of five elements in the alloy allows extra degrees of freedom, making it possible to fix the lattice constant while varying the bandgap.
33.
For optimal growth and resulting crystal quality, the crystal lattice constant " a " of each material must be closely matched, resulting in lattice-matched devices.
34.
It has cubic K 2 PtCl 6 structure, with the lattice constant a = 8.91 ? and the length of Co-F bond is 1.73 ?
35.
The compound has a melting point of 1920 �C, body-centered cubic crystal lattice and a lattice constant " a " = 1088.0 ?0.5 pm.
36.
One practical application of elastic neutron scattering / diffraction is that the lattice constant of metals and other crystalline materials can be very accurately measured.
37.
An alternative method is to grade the lattice constant from one value to another by a controlled altering of the alloy ratio during film growth.
38.
In the GaAs / AlAs system both the difference in lattice constant between GaAs and AlAs and the difference of their thermal expansion coefficient are small.
39.
In case \ Delta x = \ Delta y = \ Delta z the value \ Delta l will be used, which is the lattice constant.
40.
The lengths of the principal axes, or edges, of the unit cell and the angles between them are the lattice constants, also called " lattice parameters ".
