- In three dimensions the primitive reciprocal lattice vectors are related to the real space lattice { "'a, b, c "'} in the following way:
- The reciprocal lattice points are the values of momentum transfer where the Bragg diffraction condition is satisfied and for diffraction to occur the scattering vector must be equal to a reciprocal lattice vector.
- The vectors " G " are the reciprocal lattice vectors, and the discrete values of " k " are determined by the boundary conditions of the lattice under consideration.
- The reciprocal lattice plays a fundamental role in most analytic studies of periodic structures, particularly in the Laue conditions the momentum difference between incoming and diffracted X-rays of a crystal is a reciprocal lattice vector.
- When a single crystal is examined in an X-ray Diffractometer such that the diffraction intensity is measured cylindrically around the crystal, it is convenient to use cylindrical coordinates to define the reciprocal lattice vectors and their terminal points.
- A reciprocal lattice vector can be represented by two mutually perpendicular vectors \ zeta ( along the rotation axis ) and \ xi in the horizontal plane ( the plane perpendicular to the rotation axis ) containing the X-ray beam.
- Just the direction changes by a reciprocal lattice vector \ vec G = \ vec Q = \ vec k _ f-\ vec k _ i with the relation to the lattice spacing G = 2 \ pi / d.
- There are also " ad hoc " schemes ( e . g . in the transmission electron microscopy literature ) for indexing hexagonal " lattice vectors " ( rather than reciprocal lattice vectors or planes ) with four indices.
- In this equation, G is the reciprocal lattice vector, q is the length of the reciprocal lattice vector, k is the momentum transfer vector, ? is half of the scattering angle, and ? is the wavelength of the radiation.
- In this equation, G is the reciprocal lattice vector, q is the length of the reciprocal lattice vector, k is the momentum transfer vector, ? is half of the scattering angle, and ? is the wavelength of the radiation.
- Now, any periodic potential V ( "'r "') which shares the same periodicity as the direct lattice can be expanded out as a Fourier series whose only non-vanishing components are those associated with the reciprocal lattice vectors.
- As shown in Figure 2, " k "-vectors outside the first Brillouin zone are physically equivalent to vectors inside it and can be mathematically transformed into each other by the addition of a reciprocal lattice vector " G ".
- Where "'G "'is a reciprocal lattice vector that ensures that "'q "'falls in the first BZ and the angles ? i and ? s are measured with respect to the normal to the surface.
- For example, the reciprocal lattice vector ( hk ! ) as suggested above can be written in terms of reciprocal lattice vectors as h \ mathbf { b _ 1 } + k \ mathbf { b _ 2 } + \ ell \ mathbf { b _ 3 }.
- For example, the reciprocal lattice vector ( hk ! ) as suggested above can be written in terms of reciprocal lattice vectors as h \ mathbf { b _ 1 } + k \ mathbf { b _ 2 } + \ ell \ mathbf { b _ 3 }.
- Every crystal is a periodic structure which can be characterized by a Bravais lattice, and for each Bravais lattice we can determine the reciprocal lattice, which encapsulates the periodicity in a set of three reciprocal lattice vectors ( "'b 1, b 2, b 3 "').
- By comparing this equation with the definition of a reciprocal lattice vector, we see that constructive interference occurs if \ scriptstyle \ mathbf { K } ~ = ~ \ mathbf { k } \,-\, \ mathbf { k ^ \ prime } is a vector of the reciprocal lattice.
- Considering only ( hk ! ) planes intersecting one or more lattice points ( the " lattice planes " ), the perpendicular distance " d " between adjacent lattice planes is related to the ( shortest ) reciprocal lattice vector orthogonal to the planes by the formula : d = 2 \ pi / | \ mathbf { g } _ { h k \ ell } |.
- We notice that \ scriptstyle \ mathbf { k } and \ scriptstyle \ mathbf { k ^ \ prime } have the same magnitude, we can restate the Von Laue formulation as requiring that the tip of incident wave vector, \ scriptstyle \ mathbf { k }, must lie in the plane that is a perpendicular bisector of the reciprocal lattice vector, \ scriptstyle \ mathbf { K }.
- They are written ( hk ! ), and denote the family of planes orthogonal to h \ mathbf { b _ 1 } + k \ mathbf { b _ 2 } + \ ell \ mathbf { b _ 3 }, where \ mathbf { b _ i } are the basis of the reciprocal lattice vectors . ( Note that the plane is not always orthogonal to the linear combination of direct lattice vectors h \ mathbf { a _ 1 } + k \ mathbf { a _ 2 } + \ ell \ mathbf { a _ 3 } because the reciprocal lattice vectors need not be mutually orthogonal . ) By convention, negative integers are written with a bar, as in for " 3.
