Qiao, Shuo, Deyu Li, and Lin Yang*. "Heat Flow Guiding and Modulation by Kinks in a Silicon Nanoribbon." Nano Letters 23.19 (2023): 8860–8867.
This paper describes our research on the efficient heat flow manipulation within kinked SiNRs through carefully controlling the kink angle and arm length, which leads to distinct trends in thermal conductivity as a function of kink angle.
Lin Yang et al. "Observation of superdiffusive phonon transport in aligned atomic chains." Nature nanotechnology 16.7 (2021): 764-768.
In this paper, we present the direct experimental evidence of superdiffusive phonon transport through measuring thermal transport through ~4 nm thick NbSe3 atomic chains over 42.5 um at 300 K.
Lin Yang et al. "High thermoelectric figure of merit of porous Si nanowires from 300 to 700 K." Nature communications 12.1 (2021): 3926.
This paper reports the synthesis of large-area, wafer-scale arrays of porous silicon nanowires with ultra-thin Si crystallite size of ~4 nm. Concurrent measurements of thermal conductivity (κ), electrical conductivity (σ), and Seebeck coefficient (S) on the same nanowire show a ZT of 0.71 at 700 K, which is more than ~18 times higher than bulk Si.
Lin Yang et al. "Decoupling electron and phonon transport in single-nanowire hybrid materials for high-performance thermoelectrics." Science advances 7.20 (2021): eabe6000.
In this paper, we systematically investigate a model hybrid comprising a single core/shell nanowire of Te-PEDOT:PSS. We show the origin of the decoupling of charge and heat transport lies in the fact that electrical transport occurs through the organic shell, while thermal transport is driven by the inorganic core.
Lin Yang et al. "Distinct signatures of electron–phonon coupling observed in the lattice thermal conductivity of NbSe3 nanowires." Nano letters 19.1 (2018): 415-421.
In this paper, we show distinct signatures in the lattice thermal conductivity observed below the charge density wave transition temperatures in NbSe3 nanowires, which provides solid experimental evidence for the effects of e-ph scattering in the lattice thermal conductivity.
