Design of broadband reflector at the visible wavelengths using particle swarm optimization

AIP Advances (2019)

Shumin He Qifa Liu Tongliang Sa Zhenhai Wang

We design and theoretically investigate freestanding gallium nitride (GaN) high contrast grating (HCG) membranes as broadband reflectors operating at the visible wavelengths. Optimization of the grating structural parameters is accomplished by using particle swarm optimization (PSO), and rigorous coupled-wave analysis (RCWA) method is adopted to evaluate the optical spectrum and internal electric field intensity distribution of all structures. The proposed reflector exhibits a 99% reflectance bandwidth of 84 nm, and good angular insensitivity of about 10.2° at the wavelength of 470 nm. The tolerance of fabrication deviation is also examined by numerical analysis of the reflector performance through varying the grating structural parameters. The GaN HCG broadband reflector can be potentially assembled in GaN-based vertical cavity surface-emitting lasers (VCSELs) or other novel integrated photonic devices.

Ternary inorganic electrides with mixed bonding

Physical review. B./Physical review. B (2019)

Junjie Wang Qiang Zhu Zhenhai Wang Hideo Hosono

A high-throughput screening based on first-principles calculations was performed to search for new ternary inorganic electrides. From the available materials database, we identified three new thermodynamically stable materials (${\mathrm{Li}}_{12}{\mathrm{Mg}}_{3}{\mathrm{Si}}_{4}, {\mathrm{NaBa}}_{2}\mathrm{O}$, and ${\mathrm{Ca}}_{5}{\mathrm{Ga}}_{2}{\mathrm{N}}_{4}$) as potential electrides made by main group elements, in addition to the well known mayenite based electride (C12A7:${e}^{\ensuremath{-}}$). Different from those conventional inorganic electrides in which the excess electrons play only the role of anions, the three new materials, resembling the electrides found in simple metals under high pressure, possess mixed ionic and metallic bonding. The interplay between two competing mechanisms, together with the different crystal packing motifs, gives rise to a variety of geometries in anionic electrons and rich physical phenomena such as ferromagnetism, superconductivity, and metal-insulator transition. Our finding here bridges the gap between electrides found at ambient and high-pressure conditions.

Linearly enhanced response of thermopower in cascaded array of dual-stripe single-metal thermocouples

Applied Physics Letters (2017)

Gang Li Danhong Han Fan Yang Zhenhai Wang Yudan Pi

Based on the width dependence of thermopower, cascaded single-metal thermocouples were demonstrated in this report. The cascaded thermocouples were made from 100 nm thick Ni films with a 100 μm wide stripe and a 5 μm narrow stripe. The experiment results showed a linearly enhanced response of thermopower. The 64-cascaded thermocouple achieved an equivalent Seebeck coefficient of up to 55.69 μV/K, which is higher than that of a commercial type-K thermocouple (39.6 μV/K). The single-metal thermocouples were also fabricated on flexible substrates. With the simple fabrication process and remarkable temperature sensing ability, the cascaded single-metal thermocouples may find promising applications in temperature measurement of modern flexible electronic products and wearable devices.

Personalized starting age of gastric cancer screening based on individuals’ risk profiles: a population-based, prospective study

JNCI Journal of the National Cancer Institute (2024)

Siyi He Zhiyi Zhang Guohui Song Zhenhai Wang Li He

The current recommended starting age for gastric cancer screening lacks unified guideline and individualized criteria. We aimed to determine the risk-stratified starting age for gastric cancer screening in China based on individuals' risk profiles and to develop an online calculator for clinical application.
