Tuning the Dirac point to the Fermi level in the ternary topological insulator (Bi1โ<i>x</i>Sb<i>x</i>)2Te3
In order to stabilize Majorana excitations within vortices of proximity induced topological superconductors, it is mandatory that the Dirac point matches the Fermi level rather exactly, such that the conventionally confined states within the vortex are well separated from the Majorana-type excitation. Here, we show by angle resolved photoelectron spectroscopy โฆ
