Nano-cross-junction effect on phonon transport in silicon nanowire cages
Dengke Ma,Hongru Ding,Han Meng,Lei Feng,Yue Wu,Yue Wu,Junichiro Shiomi,Junichiro Shiomi,Nuo Yang +8 more
TL;DR: In this paper, the authors proposed a new class of three-dimensional nanostructures: a silicon-nanowirecage (SiNWC) structure consisting of silicon nanowires (SiNWs) connected by nano-cross-junctions.
Journal ArticleDOI
Low-cost high-efficiency solar steam generator by combining thin film evaporation and heat localization: Both experimental and theoretical study
Guilong Peng,Hongru Ding,Swellam W. Sharshir,Swellam W. Sharshir,Xiaojia Li,Hanchen Liu,Dengke Ma,Lirong Wu,Jianfeng Zang,Huan Liu,Wei Yu,Huaqing Xie,Nuo Yang +12 more
TL;DR: By combining heat localization and thin-film evaporation, a low-cost high-efficiency solar steam generator is proposed in this paper, where the measurements show that the energy efficiency is 78% at 1'kW/m2.
Journal ArticleDOI
Unexpected thermal conductivity enhancement in pillared graphene nanoribbon with isotopic resonance
Dengke Ma,Xiao Wan,Nuo Yang +2 more
TL;DR: In this paper, the thermal conductivity of a species of graphene nanoribbon phononic metamaterials (GNPM) was calculated through nonequilibrium molecular dynamics.
Journal ArticleDOI
Generalized Two-Temperature Model for Coupled Phonons in Nanosized Graphene
Meng An,Qichen Song,Xiaoxiang Yu,Han Meng,Dengke Ma,Ruiyang Li,Zelin Jin,Baoling Huang,Nuo Yang +8 more
TL;DR: The study gives new physical quantities, the phonon-phonon coupling factor and length, to characterize the couplings quantitatively and can not only observe the nonequilibrium between different groups of phonons but explain theoretically the thermal resistance inside nanosized graphene.
Journal ArticleDOI
Quantifying phonon particle and wave transport in silicon nanophononic metamaterial with cross junction
Dengke Ma,Anuj Arora,Anuj Arora,Shichen Deng,Guofeng Xie,Junichiro Shiomi,Junichiro Shiomi,Nuo Yang +7 more
TL;DR: In this article, the particle and wave effects on phonon transport were quantified by combining Monte Carlo and atomic Green's function methods in a one-dimensional silicon nanophononic metamaterial with cross junctions.
