Abstract Hybrid excitons formed via resonant hybridization in 2D material heterostructures feature both large optical and electrical dipoles, providing a promising platform for many‐body exciton physics correlated electronic states. However, hybrid at organic–inorganic interface combining the advantages of Wannier–Mott Frenkel remain elusive. Here, are reported copper phthalocyanine/molybdenum diselenide (CuPc/MoSe 2 ) heterostructure (HS) featuring strong molecular orientation dependence by...
Abstract Transition metal dichalcogenides (TMDs) have emerged as attractive two-dimensional semiconductors for future electronic and optoelectronic applications. Their charge transport properties, such conductivity the type of carriers, can be effectively controlled by substitutional doping transition atoms. However, effects on excitonic particularly their dynamical been less studied. Using Nb-doped MoSe 2 a case study, we experimentally investigate effect dynamics in TMDs. Transient...
We investigate the photocarrier dynamics in bulk PdSe 2 , a layered transition metal dichalcogenide with novel pentagonal structure and unique electronic optical properties.
Abstract Atomically thin transition metal dichalcogenides (TMDs) heterostructures provide a rich platform for exploring fascinating physics and engineering strategies. A pressure strategy is developed to effectively manipulate the physical properties in such heterostructures. However, there still lack of studies on corresponding pressure‐modulated evolution carrier dynamics, which crucial performance electronic optoelectronic devices. Here, utilizing diamond anvil cell, interlayer exciton...
The coherent many-body interaction at the organic-inorganic interface can give rise to intriguing hybrid excitons that combine advantages of Wannier-Mott and Frenkel simultaneously. Unlike 2D inorganic heterostructures suffer from moment mismatch, formed have a momentum-direct nature, which yet be explored. Here, we report copper phthalocyanine/molybdenum diselenide (CuPc/MoSe2) with strong molecular orientation dependence using low-temperature photoluminescence spectroscopy. new emission...
