The real-time monitoring technique of RHEED in reflection mode provides information about the surface structure of thin films because of the high surface sensitivity of the technique 9. To study the growth behaviour of thin films in real time, in situ characterization using reflection high-energy electron diffraction (RHEED) has been widely employed 8, 9. Such knowledge will enable the fabrication of electronic and optoelectronic nanodevices having specific physical properties 5, 6, 7. Understanding the growth mechanisms of nanomaterials is one of the major goals in materials science and solid-state physics 1, 2, 3, 4. This technique advances our understanding of the growth behaviour of various nanomaterials, which allows the realization of nanostructures with novel properties and their application in future electronics and optoelectronics. The structural changes in the InAs nanorods at the early growth stage caused by the transition of the local growth conditions and the strain relaxation processes that occur during epitaxial coating of the shell layers are shown. Here, as a representative study using the combined technique, the nucleation and crystallization of InAs nanorods and the epitaxial growth of In xGa 1−xAs(GaAs) shell layers on InAs nanorods are explored. Additionally, real-time monitoring by RHEED transmission mode offers a complete range of information when coupled with TEM, providing structural and chemical information with excellent spatial resolution, leading to a better understanding of the growth behaviour of nanomaterials. Such real-time observation allows the investigation of growth mechanisms of various nanomaterials that is not possible with conventional ex situ analytical methods. RHEED employed in transmission mode enables the acquisition of structural information during the growth of nanostructures such as nanorods. A novel characterization technique using both in situ reflection high-energy electron diffraction (RHEED) transmission mode and transmission electron microscopy (TEM) has been developed to investigate the growth behaviour of semiconductor nanostructures.
