Evidence for a new extended solid of nitrogen
Li Lei, Qiqi Tang, Feng Zhang +3
A new extended solid nitrogen, referred to post-layered-polymeric nitrogen (PLP-N), was observed by further heating the layered-polymeric nitrogen (LP-N) to above 2300 K at 161 GPa…
Synthesis and temperature-dependent photoluminescence of high density GeSe triangular nanoplate arrays on Si substrates
Xueyan Li, Xi Zhang, Xiaowei Lv +5
We have grown germanium selenide (GeSe) triangular nanoplate arrays (TNAs) with a high density (3.82E+6 / mm2) on the Si (111) substrate using a simple thermal evaporation method.…
Rapid Synthesis of Thermoelectric SnSe Thin Films by MPCVD
Yuyu Feng, Xi Zhang, Li Lei +2
Microwave plasma chemical vapor deposition (MPCVD) has been traditionally used to synthesize carbon-based materials such as diamonds, carbon nanotubes and graphene. Here we report…
High-pressure isostructural transition in nitrogen
Shan Liu, Meifang Pu, Qiqi Tang +3
Understanding high-pressure transitions in prototypical linear diatomic molecules, such as hydrogen, nitrogen, and oxygen, is an important objective in high-pressure physics. Recen…
Polarization Symmetry Breaking in Nitrogen under High Pressure
Meifang Pu, Li Lei
An order parameter with broken polarization symmetry is proposed for the pressure-induced molecular dissociation transitions in nitrogen. The experimental dissociative transition p…
Polycrystalline γ-boron: As hard as polycrystalline cubic boron nitride
Jiaqian Qin, Norimasa Nishiyama, Hiroaki Ohfuji +4
The Vickers hardness of polycrystalline γ-B was measured using a diamond indentation method. The elastic properties of polycrystalline γ-B (B=213.9 GPa, G=227.2 GPa, and E=503.3 GP…
Phase relations in boron at pressure up to 18 GPa and temperature up to 2200 °C
Jiaqian Qin, Tetsuo Irifune, Haruhiko Dekura +4
The phase relations in boron have been investigated at high pressure and high temperature using a multianvil apparatus, and the quenched sample has been analyzed by x-ray diffracti…
