From: Synthesis of single-unit-cell-thick perovskites by liquid-phase confined assembly for high-performance ultrastable X-ray detectors

Extended Data Fig. 1

a, Density of states of CsPbI3@(20,0)-SWCNT and projected density of states of (20,0)-SWCNT and [Cs4PbI5]. Fermi levels of CsPbI3@(20,0)-SWCNT and empty (20,0)-SWCNT are labelled, which is calculated by HSE06 functional. b, Raman spectra showing G band of CsPbI3@SWCNT and empty-SWCNT. Excitation wavelength: 532 nm.
