Torsional Instability in The Single Chain Limit of A Transition Metal Trichalcogenide

Scientific Achievement

Creation of isolated chains of NbSe3 with structural torsional waves not found in bulk crystals.

Significance and Impact

Versatile method developed to isolate single chains of 1-D van der Waals materials, and observation of Charge-Induced Torsional Waves (CTWs) in the single and few-chain limit that may find optical applications.
