Abstract
The manuscript substantiates the structural and electronic properties of covalent triazine frameworks (CTF)/As van der Waals heterostructures (vdWh) employing the standard first-principles calculation method. The numerical results designate that the CTF/As vdWh has robust crystal structures, a type-II band alignment (BA), and an indirect bandgap of 1.44 eV. The calculated results demonstrate that the strain could lead to interesting indirect-direct semiconductor transitions, while the external electric field could give rise to type-II to type-I BA and semiconductor-metal transitions. The underlined outcomes present the workability of CTF/As vdWhs in unprecedented high-performance optoelectronic equipment.
期刊介绍：
Advances in Condensed Matter Physics publishes articles on the experimental and theoretical study of the physics of materials in solid, liquid, amorphous, and exotic states. Papers consider the quantum, classical, and statistical mechanics of materials; their structure, dynamics, and phase transitions; and their magnetic, electronic, thermal, and optical properties.
Submission of original research, and focused review articles, is welcomed from researchers from across the entire condensed matter physics community.
