| 英文摘要 | A combination of experimental and computational methods was performed to investigate the defect and optical properties of S-doped and Al-doped GaSe crystals. Our experimental and calculated results indicate that the doped S and Al atoms can form S-Se and Al-Ga(+) substitutional defects in the layered GaSe structure. The non-isovalent Al-Ga(+) defect can strengthen the chemical bonding within the intralayer and induce complex defects within the interlayer in the layered GaSe structure. Al-doping maximally improves the hardness of GaSe, which makes it a promising nonlinear frequency conversion material in the infrared and THz ranges. The isovalent SSe defect determines the GaSe1-xSx mixed structure. Calculated results indicate that the refractive index of GaSe1-xSx decreases with the x value, while the band gap increases. The unique properties of GaSe1-xSx may make it a potential candidate for double heterojunction photoelectric materials. |
