Electronic and optical properties of monolayer black phosphorus induced by bi-axial strain

Anisotropic optical properties induced by uniaxial strain of monolayer C3N: a first-principles study

“…It can be seen that the optical properties of monolayer C 3 N are the same as those of two-dimensional materials such as black phosphene 45 and BC 3 , 44 which can be effectively tuned by the applied strain. However, the optical properties of these 2D monolayer materials have their own characteristics when the applied strain changes.…”

“…[60,82] On the contrary, tensile strain merely increases the bandgap of BP, while compressive strain reduces its bandgap to zero to afford an SMT. [83,84] Strain engineering can trigger changes in the electrical, optical, and thermal properties of 2D materials. [85][86][87] For example, straining increases the photoluminescence intensity of MoS 2 and ReS 2 , [54,88] and the tensile straining of MoS 2 increases its conductivity by inducing a piezoresistive effect.…”

A first-principles study of strain tuned optical properties in monolayer tellurium

“…13 It is well acknowledged that property modulation is a hot issue, especially for 2D materials. [14][15][16][17][18][19][20][21][22][23] Among those, it can be seen that strain is one of the most used methods and an effective and promising way to modify the physical properties of 2D materials. For example, local strain can modulate the optical gap and enhance light emission in ReSe 2, as well as increase visible light absorption of ScNbCO 2 .…”

“…17,18 It was also reported that optical properties in monolayer black phosphorus can be readily controlled by applying external stress. 20 Accordingly, it is likely that the physical properties of monolayer Te can be successfully tuned with strain, though such related reports are still lacking. Therefore, we adopted three phases of monolayer Te and calculated their optical properties under external biaxial strain using rst-principles calculations.…”
