"stacking friction electrical performance interfacial degradation overcome using sacrificial layer of ultra-smooth, fluid-like polymer during transfer... layer uniformly cushions allowing 2D materials to flatten smoothly/ bind perfectly to substrate without trapping air/ inducing stress... scalably prevents structural defects across large-area surfaces, preserving maximum electronic mobility and paving clear commercial path for high-performance, atom-thick semiconductor devices"
