Stress-Strain Graph Under Uniaxial and Biaxial Strain
Webthe research progress in the strain engineering of graphene. We first review the strain effects on the electronic structure and Raman spectra of graphene. We then highlight the elec-tron–phonon (e–ph) coupling greatly enhanced by the biaxial strain and the strong pseudomagnetic field induced by the non-uniform strain with specific ... WebMay 29, 2024 · Based on the calculation using first-principles, we discussed adjustment for electronic properties of the GaN/graphene/WS2 trilayer vdW heterostructure by doping and biaxial strain. Mg or Se doping can regulate the band gap of the GaN/graphene/WS2 trilayer vdW heterostructure and achieve p-type or n-type dopant in graphene and the … WebSep 1, 2024 · A relative balance of n-type and p-type thermoelectric properties of Mg 3 Sb 2 was attained.. The convergence of both conduction band and valence band of Mg 3 Sb 2 is achieved under biaxial strain.. The Seebeck coefficient of p-type Mg 3 Sb 2 has a remarkable increase, which is mainly ascribed to valence convergence.. A maximum ZT … duplicate photos lightroom
