Web8 apr. 2024 · Abstract. Polymorphic phases and collective phenomena—such as charge density waves (CDWs)—in transition metal dichalcogenides (TMDs) dictate the physical and electronic properties of the material. Most TMDs naturally occur in a single given phase, but the fine-tuning of growth conditions via methods such as molecular beam epitaxy (MBE ... Web2 dec. 2016 · HOPG step edges were selected based on edge perpendicularity relative to the AFM fast scan direction as well as straightness of the step in order to correlate experimental and simulation conditions. An upper threshold of 15° of relative rotation between the step edge and the normal of the AFM fast scan direction was chosen.
