They didn't create "half-electron". They created Majorana quasiparticles inside a superconductor.
Majorana particles are weird because they are their own antiparticle, but they are not "half-electrons". Moreover, probably neutrinos are Majorana particles, but nobody is sure, and currently there are some experiments to try to prove it.
