Images of defects at interfaces of strained Si1 - x Gex epilayers grown on bulk Si (001) substrates have been formed using the electron channelling contrast technique. The channelling images were obtained from bulk specimens using a highly efficient

Limitations on the calculation of high-resolution detail in electron microscope images of defects in crystals are discussed and it is shown how images of crystals with arbitrary strain can be calculated by means of a reinterpretation of the normal dy

To have an understanding of many imaging and diffraction effects relating to high-energy electrons it is essential to take into account the vibrations of the atoms of the solid being examined. Einstein's model of the vibrations takes the atoms to be

Weak—beam dark—field images of stacking faults in silicon vary in an interesting way as the angle of inclination of a fault to the beam changes. It is observed that the contrast of images formed with beam +g varies with angle of inclination at a

Abstract Dissociated dislocations in (111) foils of silicon have been imaged in the forbidden reflection of type ⅓(422). Largo contrast effects are observed at stacking faults, and thickness fringes corresponding to changes of thickness of a repeat

A detailed analysis of the cross-slip and annihilation of screw dislocations in B2 ordered alloys is carried out using anisotropic elasticity. The paths of the partial dislocations are calculated and it is shown that antiphase-domain boundary tubes w

An examination is made of the sharp-indentation technique of strength-test precracking for toughness evaluation. The experimental approach follows that proposed by other workers but the theoretical analysis contains one vital new feature; the residua

The structure of the NiSi2/(111)Si interface is investigated by the lattice imaging of (110) cross-sectional specimens in a JEOL 200CX transmission electron microscope with 2·4 A point-to-point resolution. NiSi2 is epitaxial and doubly-positioned on
