The effect of graphene on the activation energy of grain growth for the nanocrystalline thermoelectric n-type Bi2Te2.7Se0.3
El-Makaty, Farah M.; Pothuvattil, Nandagopal S.; Hamouda, Abdelmagid; Youssef, Khaled M. ( Springer Nature , 2022 , Article)Even though bismuth telluride is frequently produced by mechanical alloying for thermoelectric materials, no data has been published addressing the thermal behavior and activation energy of the milled n-type Bi2Te2.7Se0.3 ... -
The effect of graphene structural integrity on the power factor of tin selenide nanocomposite
Manal, Alsalama; Hamoudi, Hicham; Youssef, Khaled M. ( Elsevier , 2021 , Article)Tin selenide graphene nanocomposites (SnSe/GNPs) were fabricated with high-energy ball milling and hot pressing by varying the milling time of graphene. The effect of ball milling time on the graphene integrity and the ...
