"room-temperature... bulged substrates, which create ripples in 2D semiconductor and suppress scattering of phonons... placed 2D materials on substrates with bulged morphologies, creating ripples leads to lattice distortion... create larger electric polarization... enhance intrinsic dielectric constant... simple and cost-effective... tested on 2D molybdenum disulfide (MoS2)... mobility 900 cm2 V−1 s−1... high carrier mobility... low-powered electronics... applications ranging from field-effect transistors to photodetectors"
