It is theorized that in systems exhibiting topological superconductivity Majorana fermions exist on the surfaces and edges of the samples inside the superconducting regime, which may exhibit unique behaviors in their thermal conductivity and thermal Hall effect. The thermal Hall effect is obtained by a transverse temperature gradient when a heat current flows in the longitudinal direction. The phonon contribution to the thermal conductivity can be estimated by measurements both below and above Tc. Their difference is assumed to be the thermal carrier contribution to the thermal conductivity from the Majorana fermions. We will present the design and operation of our thermal Hall measurement setup as well as data collected on bulk 2M-WS2 samples.
