An alternative approach, used with continued success to unlock the use of diamond for semiconductor applications, has been that of 'surface transfer doping' - a process by which intrinsically insulating diamond surfaces can be made semiconducting without the need for traditional impurity doping.

In Figure 3.5a the first BZ is depicted. It has a volume of [].. Due to the translational invariance of the lattice the wave functions and the energy bands are periodic in the reciprocal space and it is sufficient to consider only the first BZ for band structure calculations [].The diamond structure is invariant not only under translations, but also under several other symmetry operations such.

C (diamond) is the prototype for DC. The Diamond Cubic (DC) unit cell can be imagined as a cube with an atom on each corner, each face, and the (¼, ¼, ¼), (¾, ¾, ¼), (¼, ¼, ¾), and (¼, ¾, ¾) positions. DC has 8 atoms per unit cell, lattice constant a = 8R/√3, Coordination Number CN = 4, and Atomic Packing Factor APF = 34%. Outline
Structure Of Diamond
The crystal structure of diamond is equivalent to a face-centred cubic (FCC) lattice, with a basis of two identical carbon atoms: one at (0, 0, 0) and the other at (1/4, 1/4, 1/4), where the coordinates are given as fractions along the cube sides. This is the same as two interpenetrating FCC lattices, offset from one another along a body.

The cubic lattice is the most symmetrical of the systems. All the angles are equal to 90°, and all the sides are of the same length (a = b = c).Only the length of one of the sides (a) is required to describe this system completely.In addition to simple cubic, the cubic lattice also includes body-centered cubic and face-centered cubic (Figure \(\PageIndex{1}\).

Lattice constant of isotope diamond have been systematically studied by two research teams. 31 - 34) The lattice constants of diamond crystals consisting of an isotopic mixture of 13 Cx 12 C(1 − x) were measured as a function of the isotopic composition by single-crystal diffractometers using synchrotron X-ray radiation. The isotope ratio of the synthesized diamond samples was determined.
