因此，GaAa的晶面和晶向的选择，会影响到表面划痕的形成。（100）晶

Therefore, the choice of GaAa crystal plane and crystal orientation will affect the formation of surface scratches. (100) The crystal plane is more prone to dissociation, that is, scratches are more likely to occur. For different crystal directions, the formation of scratches is less in the two directions of 45 ° and 135 °.

Therefore, gaAa's crystal surface and crystal direction selection, will affect the formation of surface scratches. (100) The crystal surface is more prone to dissodling, i.e. more prone to scratches. For different crystal directions, scratches are less formed in both directions, 45 and 135 degrees.

Therefore, the choice of crystal surface and orientation of GAAA will affect the formation of surface scratches. (100) the crystal surface is easier to dissociate, that is to say, it is easier to produce scratches. For different crystal directions, the formation of scratches is less in 45 ° and 135 ° directions.
