“…The maximum value of ZT for p(n)-type is 1.93(1.90) obtained along the zigzag orientation at 700 K. The high-value of ZT is acquired along the zigzag orientation in ntype and p-type due to high value of electrical conductivity and low lattice thermal conductivity. The obtained value of ZT is greater than the ZT value of SnSe 2 , SnS 2 , SnSe 2 , MoS 2 , MoTe 2 , MoSe 2 , WSe 2 , and Al2SeS [2,18,35,[42][43][44][45] as shown in Table 2. The obtained value of ZT shows that Sn 2 SeS materials are promising candidates for thermoelectric application for future reference.…”

“…The dimensionless figure of merit (ZT) can be used to assess the efficiency of thermoelectric materials. [2] In order to create high-performance thermoelectric materials, various methods have been used. Nevertheless, there is still a need to discover an effective, environmentally friendly, and costeffective method that can be used for large-scale production of these materials.…”

Abstract2D Janus materials have drawn great interest in recent years due to their energy applications including thermoelectricity (TE) and photocatalysis. In this work, density functional theory and Boltzmann transport equations are coupled to look into the thermoelectric properties of monolayer. is an indirect bandgap semiconductor with a bandgap of 0.88 eV. This monolayer is chemically as well as dynamically stable. The thermoelectric parameters such as the Seebeck coefficient, electrical conductivity, and thermal conductivity due to electrons and phonons are explored along the zigzag and armchair orientation. The high value of electrical conductivity and low‐value lattice thermal conductivity along the zigzag orientation yields the high value of ZT = 1.93.

“…A comparison of the maximum ZT values of Mo 0.9 B 2 with those of other 2D materials is shown in Fig. 6(g), and it can clearly be seen that the maximum thermoelectric performances of Mo 0.9 B 2 are significantly higher than those of other reported 2D materials, 4,62,71–78 implying high thermoelectric performance. The results show that n-type Mo 1− x B 2 has promising applications in microelectronics, wearable electronics and thermoelectric devices.…”

Designing of efficient thermoelectric material is the need of hour to avoid the adverse effect on environment. Two-dimensional (2D) transition metal oxides (TMOs) and transition metal dichalogenides (TMDCs) are receiving attention of researchers due to their wide range of electronic properties, high temperature and air stability, tunable electron transport properties for high thermoelectric efficiency (ZT). Two- dimensionalization in these materials lead to the increase in their thermoelectric efficiency as compared to their bulk counterpart due to the quantum confinement effect. These materials possess high thermoelectric efficiency even at high temperature (500-800K) but their application still lagging behind commercially due to its low ZT value. Various approaches such as strain engineering, defect engineering etc. were adopted to further enhance the ZT value of these materials. Controlling chalcogen atomic defect provides an alternative avenue for engineering a wide range of physical and chemical properties of 2D TMOs/TMDCs. In this review we will systematically present the progress made in the study of electronic, phononic, transport properties and seebeck coefficient of 2D TMOs/TMDCs such as XO2 (X=Cr, Mo, Zr) and MX2 (M= Cr, Mo, Zr; X= S, Se, Te) by using first principle approach. Methodologies such as strain engineering and doping to enhance the ZT values has also been discussed. In the last section we have discussed the experimental results of thermoelectric parameters of TMDCs and compare them with the existing theoretical results. It is concluded from this study that there are plenty of rooms which can be explored both theoretically and experimentally to design efficient thermoelectric materials for energy harvesting.
