Difference between graphics in the Zeeman effect [closed]
I've been reading articles about Zeeman's effect on TMDs specifically on WSe$_2$. In the article: Srivastava, Ajit, Sidler, Meinrad, Allain, Adrien, Lembke, Dominik, Kis, Andras, Imamoğlu, A., Valley ...
Valleys and time reversal symmetry (Zeeman effect)
Right now I'm focused on transition metal dichalcogenides. These compounds in the Brillouin zone have valleys in the valence band and in the conduction band at points K and -K. From what I've seen of ...
What is special about valley-focused Hamiltonians that make them give quantized/rational (valley) Chern numbers? [closed]
I have been thinking about so-called valley Chern numbers $C_v$ and associated topological phenomena. To my knowledge, they are usually applicable when inter-valley scattering is suppressed, leaving ...
Separation of valence bands in transition metal dichalcogenides (TMDs)
The image below refers to a phenomenon that occurs in TMDCs (transition metal dichalcogenides) monolayers that allowed the development of valleytronics. Why are there separate bands of different ...
Berry's curvature and magnetic moment in TMDCs
I am studying the transition metal dichalcogenides (TMDCs) and one of the applications that these materials have is their use in valleytronics. Valleytronics is related to the magnetic moment, Berry ...
Tools for Valleytronic Research
Similar to spintronics, which attempts to use electron spin polarization as the bits (or possibly qubits) in a logic device, valleytronics attempts to use a combination of the spin and "valleys&...
