Athermal glass work at the nanoscale: Engineered electron-beam-induced viscoplasticity for mechanical shaping of brittle amorphous silica

Kang, Sung-Gyu; Jeong, Kyeongjae; Paeng, Jeong; Jeong, Wonseok; Han, Seungwu; Ahn, Jae-Pyeong; Boles, Steven; Han, Heung Nam; Choi, In-Suk (Journal article; Peer reviewed, 2022)

Amorphous silica deforms viscoplastically at elevated temperatures, which is common for brittle glasses. The key mechanism of viscoplastic deformation involves interatomic bond switching, which is thermally activated. Here, ...
