Zn-Doped P-Type InAs Nanocrystal Quantum Dots

Lior Asor et al.

Summary: Doped heavy metal-free III-V semiconductor nanocrystal quantum dots (QDs) have attracted great interest for both their fundamental doping characteristics and their applicability in p-n homojunction devices. In this study, p-type doping of InAs NCs was achieved through the use of Zn, allowing for control over the charge carrier type in InAs QDs field effect transistors. X-ray absorption spectroscopy analysis confirmed substitutional doping by Zn2+ replacing In3+. Surface passivation by Zn was also observed, leading to enhanced near infrared photoluminescence. This research paves the way for the fabrication of optoelectronic devices active in the short-wave infrared region using heavy-metal free nanocrystal building blocks.

ZnCl2 Mediated Synthesis of InAs Nanocrystals with Aminoarsine

Dongxu Zhu et al.

Summary: This study investigates the role of ZnCl2 as an additive in the synthesis of InAs nanocrystals (NCs) using tris(dimethylamino)arsine. It is found that ZnCl2 not only improves the size distribution of InAs NCs, but also acts as a ligand to passivate their surface. The addition of a Zn precursor enables the subsequent growth of a ZnSe shell, resulting in InAs@ZnSe core@shell NCs with high quantum yield.

Efficient Short-Wave Infrared Light-Emitting Diodes Based on Heavy-Metal-Free Quantum Dots

Xiaofei Zhao et al.

Summary: Short-wave infrared (SWIR) light emission is important for various modern applications. However, there are limited semiconductors that can efficiently emit SWIR light. This study presents a highly efficient SWIR LED based on heavy-metal-free indium arsenide (InAs) core-shell colloidal quantum dots (CQDs), achieving high external quantum efficiencies through the implementation of a poly(vinylcarbazole) layer.

Regulating Thiol Ligands of p-Type Colloidal Quantum Dots for Efficient Infrared Solar Cells

Jingxuan Chen et al.

Summary: This study investigates a series of thiol ligands for p-type CQDs, demonstrating that by carefully controlling the interaction between CQDs and thiol ligands during the preparation of p-type CQD solid films, the n-type CQD solid films can be effectively protected from destruction induced by thiol ligands. The p-type CQD solid film passivated with 4-aminobenzenethiol (ABT) shows better optoelectronic properties than conventional EDT-based films, leading to improved photovoltaic performance in CQDSCs.

Ultra-Confined Visible-Light-Emitting Colloidal Indium Arsenide Quantum Dots

Daryl Darwan et al.

Summary: A method of preparing highly luminescent visible-light-emitting quantum dots using a low-temperature nanocluster synthesis approach has been developed. The strong confinement effects in the few-atom-wide nanoclusters are responsible for the significant spectral shift from the near-infrared to the visible region, suggesting broader-than-expected optical tuning may be achievable in other quantum-confined semiconductor systems.

Diffusion dynamics controlled colloidal synthesis of highly monodisperse InAs nanocrystals

Taewan Kim et al.

Summary: A growth model based on monomer diffusion dynamics was proposed to synthesize colloidal InAs QDs with a size over 9.0 nm and a narrow size distribution. By controlling the diffusion dynamics, the authors were able to overcome the size limitation of nanocrystal growth in solution and extend the spectral coverage of InAs QDs beyond 1S(max) of 1600 nm.

InAs Nanocrystals with Robust p-Type Doping

Lior Asor et al.

Summary: This study demonstrates the successful p-type doping of originally n-type InAs nanocrystals by post-synthetically doping with Cd, showing remarkable stability of hole conduction, mobility, and hysteretic behavior in Cd-doped InAs FETs compared to intrinsic InAs NCs FETs when exposed to air. Cd acts as a p-type dopant and also protects the nanocrystals from oxidation, setting the stage for implementing doped nanocrystal systems in printed electronic devices.
