2D II-VI Semiconductor Nanoplatelets: From Material Synthesis to Optoelectronic Integration

Benjamin T. Diroll et al.

Summary: The field of colloidal synthesis of semiconductors has matured over the past 40 years, especially in the production of II-VI semiconductor nanocrystals with tailored shapes and compositions. II-VI semiconductor nanoplatelets have become narrow room-temperature emitters with good stability over time. They exhibit interesting features at the intersection of colloidal quantum dots and epitaxial quantum wells. This review discusses the synthetic developments, spectroscopic properties, and applications of such nanoplatelets.

Two-Dimensional CdSe-PbSe Heterostructures and PbSe Nanoplatelets: Formation, Atomic Structure, and Optical Properties

Bastiaan B. Salzmann et al.

Summary: This study prepared two-dimensional CdSe-PbSe heterostructures and PbSe NPLs through Pb2+-for-Cd2+ cation exchange and characterized the intermediary NCs with advanced microscopy and spectroscopy techniques. The growth of PbSe domains in CdSe NPLs occurs through the replacement of zinc blende CdSe lattice with rock salt PbSe phase while preserving the anion sublattice. Temperature-dependent emission measurements reveal size-dependent change of band gap energy and the influence of the anisotropic shape.

Colloidal 2D PbSe nanoplatelets with efficient emission reaching the telecom O-, E- and S-band

Lars F. Klepzig et al.

Summary: This study demonstrated a direct synthesis route for 2D cubic rock salt structure PbSe nanoplatelets, with controllable lateral size tuning achieved by controlling temperature and adding octylamine. Post-synthetic treatment significantly improved the photoluminescence quantum yield of the PbSe nanoplatelets, while reducing the surface trap related PL contribution.

Dielectrically Confined Stable Excitons in Few-Atom-Thick PbS Nanosheets

Tharaka M. D. S. Weeraddana et al.

Summary: Two-dimensional colloidal PbS nanosheets have a significantly higher exciton binding energy than their bulk counterpart, allowing for the generation of stable excitons at room temperature. The binding energy of the exciton increases as the thickness of the PbS nanosheet decreases, due to dielectric confinement. This large binding energy leads to a faster exciton radiative recombination rate, which has been confirmed experimentally.

Toward Bright Colloidal Near-Infrared Emitters: Surface Passivation of 2D PbSe Nanoplatelets by Metal Halides

Leon Biesterfeld et al.

Summary: Treatment with metal halides can improve the emission brightness and optical properties of colloidal 2D PbSe nanoplatelets. Surface passivation leads to a significant increase in photoluminescence quantum yield and a decrease in full width at half-maximum. This has important implications for the application of 2D PbSe NPLs in fiber optics.

Graphene/Quantum Dot Heterostructure Photodetectors: From Material to Performance

Mao-Kun Zhang et al.

Summary: Graphene is an ideal material for photodetection due to its high carrier mobility and stability, but its weak light absorption hinders its practical applications. To overcome this limitation, quantum dots are hybridized with graphene to achieve wide-range and intense light absorption. In this paper, the significance, synthesis methods, and performance engineering strategies of graphene/quantum dot heterostructure photodetectors are systematically discussed.

Exciton States and Optical Absorption in CdSe and PbS Nanoplatelets

Davit A. Baghdasaryan et al.

Summary: This paper theoretically investigates the exciton states and their influence on the optical absorption spectrum of CdSe and PbS nanoplatelets. The problem is discussed in different size quantization regimes, and the corresponding potential that describes the electron-hole interaction in this mode of space quantization is chosen. The study reveals single-particle energy spectra, wave functions, and the dependence of material parameters on the number of monolayers in the sample. The effect of dielectric coefficient mismatch and different electron-hole interaction potentials are also studied.

Light-Emitting Diodes Based on Two-Dimensional Nanoplatelets

Yating Guo et al.

Summary: Colloidal semiconductor nanocrystals have attracted significant interest in display technologies due to their narrow and tunable emission wavelength and high photoluminescence quantum yield. However, the low out-coupling factor of nanocrystal LEDs using spherical quantum dots presents a challenge in enhancing device performance. Anisotropic nanoplatelets are proposed as promising solutions to improve the performance of nanocrystal LEDs.

Morphology and Band Structure of Orthorhombic PbS Nanoplatelets: An Indirect Band Gap Material

David F. Macias-Pinilla et al.

Summary: Research shows that colloidal PbS NPLs may have an orthorhombic crystal structure instead of the rock-salt structure found in bulk materials. Calculations indicate that quantum confinement along the a crystallographic axis strengthens the indirect band gap, while confinement along the b and c axes favors a direct band gap.
