Idealizing Tauc Plot for Accurate Bandgap Determination of Semiconductor with UV-Vis: A Case Study for Cubic Boron Arsenide
Hong Zhong, Fengjiao Pan, Shuai Yue +8
The Tauc plot method is widely used to determine the bandgap of semiconductors via UV-visible optical spectroscopy due to its simplicity and perceived accuracy. However, the actual…
Theory and Experiments of Pressure-Tunable Broadband Light Emission from Self-Trapped Excitons in Metal Halide Crystals
Shenyu Dai, Xinxin Xing, Viktor G. Hadjiev +9
Hydrostatic pressure has been commonly applied to tune broadband light emissions from self-trapped excitons (STE) in perovskites for producing white light and study of basic electr…
Marangoni Convection-Driven Laser Fountains and Waves on Free Surfaces of Liquids
Feng Lin, Aamir Nasir Quraishy, Tian Tong +18
It is well accepted that an outward Marangoni convection from a low surface tension region will make the surface depressed. Here, we report that this established perception is only…
Photoacoustic Identification of Laser-induced Microbubbles as Light Scattering Centers for Optical Limiting in Liquid Suspension of Graphene Nanosheets
Qiuhui Zhang, Yi Qiu, Feng Lin +8
Liquid suspensions of carbon nanotubes, graphene and transition metal dichalcogenides have exhibited excellent performance in optical limiting. However, the underlying mechanism ha…
Self-formed 2D/3D Heterostructure on the Edge of 2D Ruddlesden-Popper Hybrid Perovskites Responsible for Intriguing Optoelectronic Properties and Higher Cell Efficiency
Zhaojun Qin, Shenyu Dai, Chalapathi Charan Gajjala +15
The observation of low energy edge photoluminescence and its beneficial effect on the solar cell efficiency of Ruddlesden-Popper perovskites has unleashed an intensive research eff…
Photoluminescence mapping and time-domain thermo-photoluminescence for rapid imaging and measurement of thermal conductivity of boron arsenide
Shuai Yue, Geethal Amila Gamage, Mohammadjavad Mohebinia +14
Cubic boron arsenide (BAs) is attracting greater attention due to the recent experimental demonstration of ultrahigh thermal conductivity \k{appa} above 1000 W/mK. However, its ban…
Graphene Induced Large Shift of Surface Plasmon Resonances of Gold Films: Effective Medium Theory for Atomically Thin Materials
Md Kamrul Alam, Chao Niu, Yanan Wang +15
Despite successful modeling of graphene as a 0.34-nm thick optical film synthesized by exfoliation or chemical vapor deposition (CVD), graphene induced shift of surface plasmon res…
Revealing the Origin of Luminescence Center in 0D Cs4PbBr6 Perovskite
Zhaojun Qin, Shenyu Dai, Viktor G. Hadjiev +13
Zero dimensional perovskite Cs4PbBr6 has attracted considerable attention recently not only because of its highly efficient green photoluminescence (PL), but also its two highly de…
Laser Streaming: Turning a Laser Beam into a Flow of Liquid
Yanan Wang, Qiuhui Zhang, Zhuan Zhu +9
Transforming a laser beam into a mass flow has been a challenge both scientifically and technologically. Here we report the discovery of a new optofluidics principle and demonstrat…
