چکیده	Using the tight-binding approach and non-equilibrium Green’s function method, we investigate the electronic band structure, total electronic heat capacity (EHC), and Pauli spin susceptibility (PSS) of zigzag MoS2/MoSe2 and MoS2/WSe2 hybrid nanoribbons in the presence of transverse electric and external exchange fields. Our results show that in the simultaneous presence of both of these fields, the zigzag MoS2/WSe2 and MoS2/MoSe2 nanoribbons are converted to half-metal systems. The total EHC increases with growing temperature until the Schottky anomaly appears at 150 K. we show that these hybrid nanoribbons become almost antiferromagnetic with the Neel temperature of 200 K. Interestingly, in the whole range temperature, the total EHC and PSS decrease by the transverse electric and external exchange fields. Our results provide an efficient and practical approach to the design of spintronic devices.
