Key points to answer this question : Edges of unit cell and the angles between the Edges of unit cell are the main points to characterize a unit cell.
so we can answer this asked question as follows –
answer : A unit cell is characterize by following factors –
- The dimensions of unit cell along the three edges a , b , and c (showing in the figure below)
- The angles between the edges α , β , γ. (here α is angle between edge b and c , β is angle between edge a and c , γ is angle between edge a and b)
so we can say that any unit cell can be characterized by six parameters which are a , b , c and α , β , γ.
which includes the edges and angles between the edges of unit cell showed in figure below –
parameters of unit cell figure.
