Vertex directed analysis of the hidden state relaxation in 1T-TaS2

Andrej Kranjec, Department for Complex Matter, JSI

Abstract:

I will be presenting a brief summary of our latest results obtained by applying a global interdomain shifts recognition algorithm on a high quality STM sequence of the relaxation of the H-state in 1T-TaS₂. We show how the results of the algorithm provide a basis for the study of dislocations by determining trivial and non-trivial vertices where domain walls meet by constructing Burgers circuits and vectors around selected vertices. The analysis shows that some of the relaxation dynamics could be consistent within the scope of dislocation theory.
