GaAs:Zn whiskers grown by the gas-transport method are characterized by diffraction methods using white and monochromatic radiation. The methods applied include the white-beam topography at ESRF synchrotron source and Laue patterns, 4-circle Bond diffractometry and high-resolution diffractometry at conventional X-ray sources. The results obtained concern the growth morphology and defect structure. It is found that GaAs:Zn whiskers grown by the described method have the form of long needles and blades of the morphologies represented by growth direction and largest lateral face ⟨112⟩{111} and ⟨111⟩{112}, respectively, with a single exception of a blade of uncommon morphology ⟨111⟩{110}.
