Heterovalent cation substitutional doping for quantum dot homojunction solar cells
Colloidal quantum dots have emerged as a material platform for low-cost high-performance optoelectronics. At the heart of optoelectronic devices lies the formation of a junction, which requires the intimate contact of n-type and p-type semiconductors. Doping in bulk semiconductors has been largely deployed for many decades, yet electronically active doping in quantum dots has remained a challen...
متن کاملSubstitutional Doping for Aluminosilicate Mineral and Superior Water Splitting Performance
Substitutional doping is a strategy in which atomic impurities are optionally added to a host material to promote its properties, while the geometric and electronic structure evolution of natural nanoclay mineral upon substitutional metal doping is still ambiguous. This paper first designed an efficient lanthanum (La) doping strategy for nanotubular clay (halloysite nanotube, HNT) through the d...
متن کاملEffect of substitutional doping on the Néel temperature of Cr2O3
First-principles calculations are used to explore the possibility of enhancing the Néel temperature T N of the magnetoelectric antiferromagnet Cr 2 O 3 by substitutional doping. We describe the electronic structure of transition metal (V, Ti, Mn, Fe, Co, and Ni) and anion (N and B) impurities and evaluate their effect on the exchange interaction. We find that, although transition-metal impuriti...
متن کاملAtomically controlled substitutional boron-doping of graphene nanoribbons
Boron is a unique element in terms of electron deficiency and Lewis acidity. Incorporation of boron atoms into an aromatic carbon framework offers a wide variety of functionality. However, the intrinsic instability of organoboron compounds against moisture and oxygen has delayed the development. Here, we present boron-doped graphene nanoribbons (B-GNRs) of widths of N=7, 14 and 21 by on-surface...
متن کاملMonovalent Cation Doping of CH3NH3PbI3 for Efficient Perovskite Solar Cells
Here, we demonstrate the incorporation of monovalent cation additives into CH3NH3PbI3 perovskite in order to adjust the optical, excitonic, and electrical properties. The possibility of doping was investigated by adding monovalent cation halides with similar ionic radii to Pb2+, including Cu+, Na+, and Ag+. A shift in the Fermi level and a remarkable decrease of sub-bandgap optical absorption, ...
