The tensile strain is proved to be an efficient way to modulate the band structure.
Our calculations reveal that it is possible to intentionally modulate the band structures of PbTe by appropriate collocation of dual-doping atoms for improved thermoelectric properties.
Symmetry breaking induced by the in-plane strain not only modulates the band structure, but also changes the carrier population at the valence band maximum and conduction band minimum so that the transport current density can be regulated.
Fluorinated C60 (F-C60) is a p-type organic semiconductor with a deep highest occupied molecular orbital (HOMO) level and it was used to modulate the band structure of reduced graphene oxide (rGO).
Introduction of very low nitrogen concentrations is sufficient to modulate the band gap of such systems over a wide range.
Moreover, it provides a promising strategy for modulating the band positions of RGO. Figure 4 Mechanism of in-situ photoelectrochemical reduction of GO in a DSSC assembly.
Doping of graphene with other heteroatoms (e.g., nitrogen, boron, phosphorus, halogen, etc). is the most practicable, convenient, and efficient approach to modulate the band structure and properties of graphene [7] and further extend more useful applications in electronics and electrochemical cells [8, 9, 10, 11, 12, 13].
(B) Schematic of the A1g phonon mode (top), which periodically modulates the electronic band energies (bottom).
Herein, we demonstrate that C3N4-W18O49, the type-II composite, can be switcompositeirecanZ-scheme via modulating the interfacial bend bending.
