Thermoelectric properties of Bi2Se3/Bi2Te3/Bi2Se3 and Sb2Te3/Bi2Te3/Sb2Te3 quantum well systems
Yelgel, Övgü Ceyda; Srivastava, Gaurav Prakash (Taylor & Francis Ltd, 2014)In this work, we develop a theory of thermoelectric transport properties in two-dimensional semiconducting quantum well structures. Calculations are performed for n-type 0.1 wt.% CuBr-doped Bi2Se3/Bi2Te3/Bi2Se3 and p-type ... -
Thermoelectric properties of Mg2X (X = Si, Ge) based bulk and quantum well systems
Yelgel, Övgü Ceyda (Amer Inst Physics, 2017)Mg2X (X = Si, Ge) compounds are promising thermoelectric materials for middle temperature applications due to good thermoelectric properties, nontoxicity, and abundantly available constituent elements. So far, these materials ... -
Thermoelectric transport behaviours of n-type Mg-2 (Si,Sn,Ge) quaternary solid solutions
Yelgel, Övgü Ceyda; Yelgel, Celal (Keai Publishing Ltd, 2019)Mg2X (X=Si, Sn, and Ge) based systems have attracted widespread attention owing to their various benefits in thermoelectric applications. in particular, to date, ternary Mg2X based solid solutions have become one of the ... -
