“…Notably, no Ag 2 Te peak can be observed, which is in contrast to typical scans from AgSbTe 2 samples. 28 This observation can be ascribed to the phase diagram in Fig. 1 which shows that with increasing annealing temperature above 633 K, Ag 2 Te-deficient samples tend to form a stable phase of Ag 1−x Sb 1+x Te 2+x .…”

“…Notable among these are compounds based on GeTe, SnSe, Cu 2 Se, Mg 3 Sb 2 , and AgSbTe 2 . [25][26][27][28][29][30][31][32][33][34][35][36][37] In particular, AgSbTe 2 can potentially be used for both near room temperature and medium temperature applications, making it a versatile high performance thermoelectric material. [38][39][40][41][42][43][44][45][46] Due to the high intrinsic Seebeck coefficient and low intrinsic thermal conductivity, high thermoelectric performance can be achieved in AgSbTe 2 even in the absence of doping.…”

“…10(c), that S declines dramatically at low carrier concentrations with the excitation of carriers at high temperatures, and the peak value of S shifts towards higher carrier concentrations. Compared to the common Janus TE materials, such as PbSSe with 6% strain (209.52 μV K −1 ), 69 MoSSe (240 μV K −1 ), 70 SnSSe with 8% strain (189.03 μV K −1 ), 71 and AgSbTe 2 (250 μV K −1 at ∼ 330 K), 72 Janus MXTe monolayers with similar S values will possess excellent TE performance.…”
Two-dimensional (2D) materials have garnered significant attention in recent thermoelectric studies. The Janus 2H-MXTe (M = Zr and Hf; X = S and Se) monolayers, as the 2D materials with classic configuration, have demonstrated exceptional thermoelectric performance in theoretical studies.
“…17 In the past decades, significant development of thermoelectric technology has focused on the enhancement of zT. [18][19][20] The zT is highly temperature-dependent, 21,22 which determines their applicability to function under different scenarios and temperature regions. According to the application temperature region, thermoelectric materials can be categorized into near roomtemperature (T o 500 K), mid-temperature (500 r T o 800 K), and high-temperature (T Z 800 K) types.…”
Nanoengineering is an effective strategy to strengthen phonon scattering, reduce lattice thermal conductivity and boost thermoelectric material performance. However, nanostructure features are generally in the size of ~10 nm, and...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
