Fig. 2: Properties of MoS2 nanobubbles obtained from MD simulations.
From: Tunable strain and bandgap in subcritical-sized MoS2 nanobubbles
a Bubble profiles with varying sizes, R. The profile for R = 21.0 nm is fitted by adopting the model proposed by Blundo et al.27. b Evolution of the h/R ratio as a function of R. c Calculated hydrostatic pressure, P, inside relaxed MoS2 nanobubbles of different sizes (Supplementary Fig. 3). The gray line obtained by exponential regression provides a visual guide. Each data point in (b, c) accounts for one MD bubble. d RPDFs of the atoms trapped between the MoS2 and the Au(111) substrate for different bubble sizes, where r* stands for the distance from a reference atom38 The color scheme follows that given in (a).
