High-performance green and blue quantum-dot light-emitting diodes with eliminated charge leakage
Yunzhou Deng, Feng Peng, Yao Lu +12
Quantum-dot light-emitting diodes (QD-LEDs) promise a new generation of efficient, low-cost, large-area, and flexible electroluminescent devices. However, the inferior performance…
Ultrahigh Pressure Superconductivity in Molybdenum Disulfide
Zhenhua Chi, Feihsiang Yen, Feng Peng +9
Superconductivity commonly appears under pressure in charge density wave (CDW)-bearing transition metal dichalcogenides (TMDs), but has emerged so far only via either intercalation…
Stable Xenon Nitride at High Pressures
Feng Peng, Yanchao Wang, Hui Wang +2
Nitrides in many ways are fascinating since they often appear as superconductors, high energy density and hard materials. Though there exist a large variety of nitrides, noble gas…
Tuning of Quantum Paraelectricity of M-type Hexaferrite BaFe12O19 by External Parameters
Jing Zhang, Feng Peng, Na Su +5
M-type hexaferrite BaFe12O19 was recently reported to be a new type of quantum paraelectrics with triangular lattice by showing a low temperature dielectric plateau due to quantum…
High-pressure Phase Stability and Superconductivity of Pnictogen Hydrides and Chemical Trends for Compressed Hydrides
Yuhao Fu, Xiangpo Du, Lijun Zhang +7
Binary hydrides formed by the pnictogens of phosphorus, arsenic and antimony are studied at high pressures using first principles methods. Stable structures are predicted and their…
Experimental Syntheses of Sodalite-like Clathrate EuH and EuH at Extreme Pressures
Liang Ma, Guangtao Liu, Yingying Wang +5
The recent discovery of a class of sodalite-like clathrate superhydrides (e.g., YH6, YH9, ThH9, ThH10, and LaH10) at extreme pressures, which exhibit commonly a high-temperature su…
High-pressure hybrid materials that can store hydrogen in table salt
Feng Peng, Yanming Ma, Maosheng Miao
We demonstrate in this paper that high pressure can promote the reactions between the ionic compounds and H2 molecules and form thermodynamically stable hybrid compounds. Using cry…
Principle and performance analysis of the Levenberg Marquardt algorithm in WMS spectral line fitting
Yongjie Sun, Tingting Zhang, Kun Li +3
Calibration free wavelength modulation spectroscopy (WMS) is an efficient technique for trace gas monitoring. It is widely used due to its resistance to light intensity fluctuation…
NH: A Novel Polymeric Hydronitrogen as a High Energy Density Material
Ketao Yin, Yanchao Wang, Hanyu Liu +2
The polymeric phase of nitrogen connected by the lower (than three) order N-N bonds has been long sought after for the potential application as high energy density materials. Here…
