Intrinsic bandgap
WebJun 29, 2024 · However, pure blue-emitting MHPs with an emission wavelength of approximately 465 nm are intrinsically difficult to synthesize using only single-halide 3D MHPs. Pure chloride-containing 3D MHPs exhibit a deep blue-violet emission spectrum (~409 nm) with a wide bandgap (3.16 eV) [37,38]. WebThe optical absorption measurements demonstrate that an intrinsic bandgap of 2.5 ± 0.3 eV could be achieved in such a semiconducting state, and once opened could be preserved to a few GPa. The realization of wide bandgap in compressed trilayer graphene offers opportunities in carbon-based electronic devices.
