Emergent grain boundary phases in stressed polycrystalline thin films
Mengyuan Wang, Ruilin Yan, Xiao Han +2
The grain boundary (GB) microstructure influences and is influenced by the development of residual stresses during synthesis of polycrystalline thin films. Recent studies have show…
Microgroove convexity is critical for robust gaseous layers on hierarchically-structured superhydrophobic surfaces
Xiao Han, Jingnan Liu, Moneesh Upmanyu +1
Gaseous layers (plastrons) trapped on the surfaces of immersed hydrophobic surfaces are critical for their function. Fibrillar morphologies offer a natural pathway, yet they are li…
Tuning nanoscale adhesive contact behavior to a near ideal Hertzian state via graphene coverage
Yongchao Chen, Zhizi Guan, Yongtao Yao +1
We carry out molecular statics (MS) simulations to study the indentation process of Pt (111) surfaces using an indenter with the radius of 5-20 nm. The substrate and indenter surfa…
Stability and energetics of 2D surface crystals in liquid AuSi thin films and nanoscale droplets
Hailong Wang, Alireza Shahabi, Alain Karma +1
Segregation at surfaces of metal-covalent binary liquids is often non-classical and in extreme cases such as AuSi, the surface crystallizes above the melting point. In this study,…
Atomistics of vapor-liquid-solid nanowire growth
Hailong Wang, Luis A. Zepeda-Ruiz, George H. Gilmer +1
Vapor-liquid-solid (VLS) route and its variants are routinely used for scalable synthesis of semiconducting nanowires yet the fundamental growth processes remain unknown. Here, we…
Saddles, Twists, and Curls: Shape Transitions in Freestanding Nanoribbons
Hailong Wang, Moneesh Upmanyu
Efforts to modulate the electronic properties of atomically thin crystalline nanoribbons requires precise control over their morphology. Here, we perform atomistic simulations on f…
