Growth and transport properties of oriented bismuth telluride films

Multilayered structure and enhanced thermoelectric properties of Bi1.5 Sb0.5 Te3 film with preferential growth

“…4(a), indicating a metallic like behavior. This is similar to the Bi 2 Te 3 -based materials [12,13] and the (0 1 5)-oriented Bi 1.5 Sb 0.5 Te 3 film [see Fig. 4(a)].…”

Effect of point defects on the electronic density of states of ScN studied by first-principles calculations and implications for thermoelectric properties

“…15 This power factor is very large when comparing to a state-of-the-art thermoelectric material such as Bi 2 Te 3 or PbTe. 16,17 Moreover, ScN has been shown to have suitable mechanical and electrical properties. [18][19][20][21][22][23][24][25][26][27] We also reported effects on thermoelectric properties of ScN with small changes in the composition with the power factor changing one order of magnitude depending on, for example, oxygen, carbon, and fluorine content.…”

Effect of Ag-doping on crystal structure and high temperature thermoelectric properties of c-axis oriented Ca3Co4O9 thin films by pulsed laser deposition

“…Nevertheless, it is found that thin film configuration with well controlled crystal orientation can cater for the electrical transport of carriers along favorable direction and overcome this issue. In addition, thin films can promote the reduction of thermal conductivity by phonon scattering effect [6], and facilitates Micro-Electro-Mechanical System (MEMS) processing towards on-chip devices [7]. Epitaxial or c-axis oriented Ca 3 Co 4 O 9 thin films have been prepared by various techniques, such as radiofrequency (RF) sputtering [8], pulsed laser deposition (PLD) [9,10], atomic layer deposition (ALD) [11] and topotactic ion-exchange method [12].…”
