“…The behavior observed is characteristic of phase transitions. [1][2][3][4][5][6][7]60,61 Such anomalies in electrical conductivity were similarly observed in nanostructures based on Bi 2 Te 3 , 6,42 Bi 2 Te 3 single crystals doped with Tl, 29 and Fe. 30 The anomaly was almost invisible on the undoped single crystal (Figure 2).…”

The temperature dependences of the electrical conductivity (T), Seebeck coefficient (T), and heat capacity C p (T) of polycrystalline samples of Bi 2 Te 3 , Bi 2 Te 3 +1%CuI, and Bi 2 Te 3 +1%(CuI+1/2Pb) are investigated in the temperature range below room temperature. Based on the temperature dependences of all investigated physical properties, it is discovered that phase transition occurs at 120-200 K. Investigation of single crystals shows that anomalies in the electrical resistivity ( (T) = 1∕ (T)) occur only across the crystal growth axis (across the well-conducting Bi-Te plane).Investigation of the low-temperature dependence of electrical conductivity shows that all polycrystalline samples exhibit quasi-two-dimensional electron transport. Additionally, quasi-two-dimensional transport is detected in single crystals based on anisotropy analysis ⊥ (T)∕ ‖ (T): 10 (where ‖ (T) is the resistivity along the crystal growth axis, and ⊥ (T) is resistivity across the crystal growth axis) and temperature dependence (T): T 2 below 50 K. The Fermi energy E F is estimated using the temperature dependence of S(T). It is discovered that an increase in E F at T > 200 K is associated with the phase transition. For single-crystal samples, the maximum thermoelectric figure of merit ZT, as observed along the crystal growth axis, increases with doping. A maximum ZT value of ~1.1 is observed for the Bi 2 Te 3 +1%(CuI+1/2Pb) sample at room temperature (T = 300 K).

“…One such example is molybdenum sesquisulfide Mo 2 S 3 . [21][22][23][24][25] Bulk Mo 2 S 3 shows unusual electron transport properties at low temperatures due to the metal cluster formation, [26][27][28][29][30] and it has been suggested for use as an element for memory devices. 31 More recently, Mo 2 S 3 was investigated as a cathode material.…”
