TL;DR: In this paper, the authors proposed a far-field light microscope with nanoscale resolution, which is capable of observing the molecular processes of life in 3D-imaging of the interior of live cells.
Abstract: In 1873, Ernst Abbe discovered that the resolution of focusing (‘far-field’) optical microscopy is limited to d = λ/(2nsinα ) > 200 nm, with nsinα denoting the numerical aperture of the lens and λ the wavelength of light While the diffraction barrier has prompted the invention of electron, scanning probe, and x-ray microscopy, in the life sciences 80% of all microscopy studies are still performed with lens-based (fluorescence) microscopy The reason is that the 3D-imaging of the interior of (live) cells requires the use of focused visible light Hence, besides being a fascinating physics endeavor, the development of a far-field light microscope with nanoscale resolution would facilitate observing the molecular processes of life

TL;DR: In this paper, the authors discuss the factors affecting instability of perovskite and give some perspectives about further enhancement of stability of pervskite solar cell, which is a promising next generation photovoltaic technology.
Abstract: Organo lead halide perovskite materials like methylammonium lead iodide (CH3NH3PbI3) and formamidinium lead iodide (HC(NH2)2PbI3) show superb opto-electronic properties. Based on these perovskite light absorbers, power conversion efficiencies of the perovskite solar cells employing hole transporting layers have increased from 9.7% to 20.1% within just three years. Thus, it is apparent that perovskite solar cell is a promising next generation photovoltaic technology. However, the unstable nature of perovskite was observed when exposing it to continuous illumination, moisture and high temperature, impeding the commercial development in the long run and thus becoming the main issue that needs to be solved urgently. Here, we discuss the factors affecting instability of perovskite and give some perspectives about further enhancement of stability of perovskite solar cell.

TL;DR: In this paper, a review of 2D molybdenum disulfide (MoS2) properties is presented, focusing on the indirect to direct band-gap transition from bulk and few-layer structures to mono-layered MoS2.
Abstract: The emergence of two-dimensional (2D) materials has led to tremendous interest in the study of graphene and a series of mono- and few-layered transition metal dichalcogenides (TMDCs). Among these TMDCs, the study of molybdenum disulfide (MoS2) has gained increasing attention due to its promising optical, electronic, and optoelectronic properties. Of particular interest is the indirect to direct band-gap transition from bulk and few-layered structures to mono-layered MoS2, respectively. In this review, the study of these properties is summarized. The use of Raman and Photoluminescence (PL) spectroscopy of MoS2 has become a reliable technique for differentiating the number of molecular layers in 2D MoS2.

TL;DR: In this paper, the authors review the work on heterogeneous III-V-on-silicon photonic components and circuits for applications in optical communication and sensing and elaborate on the integration strategy and describe a broad range of devices realized on this platform.
Abstract: In the paper, we review our work on heterogeneous III-V-on-silicon photonic components and circuits for applications in optical communication and sensing. We elaborate on the integration strategy and describe a broad range of devices realized on this platform covering a wavelength range from 850 nm to 3.85 μm.
