Experimental investigation of the developed focusing elements for generating extreme pressures in a diaphragmless shock tube
Physical model
The shape of the shock wave front moving through the slowly varying area of the shock tube changes due to disturbances generated by the wall. Since the effects of these disturbances in the shock wave formation regions dominate over…

Reversible switching of the environment-protected quantum spin Hall insulator bismuthene at the graphene/SiC interface
Electronic and geometric properties of the precursor phase
We start with a discussion of the properties of the precursor phase, which is prepared by Bi intercalation of a graphene buffer layer and several subsequent annealing steps (see Methods…
