Substrate-induced strain and exchange field effects on the electronic and thermal properties of monolayer β12-borophene
We are happy to announce that Prof. Tran Cong Phong and colleagues recently published their work entitled "Substrate-induced strain and exchange field effects on the electronic and thermal properties of monolayer β12-borophene" in the Physical Chemistry Chemical Physics
Abstract:
The recently uncovered two-dimensional materials serve as versatile building blocks for electronic devices. In this study, we methodically investigate the impact of substrate-induced strain and exchange field effects on the electronic density of states (EDOS) and electronic heat capacity (EHC) of single-layer β12-borophene. Utilizing the Green's function approach, we compute these functions. The van Hove singularities in EDOS are observed to shift with strain, and depending on the direction and strength of the exchange field, the number of singularities increases. All these responses can be attributed to the renormalization of the velocity of electronic bands. Additionally, the inherent Schottky anomaly (an unusual peak at low temperatures) in the EHC undergoes a notable shift to higher and lower temperatures and variations in the intensity of the EHC due to substrate effects.
