“…Along with many low-dimensional semiconductors fabricated and used on the basis of such structures as quantum wells, quantum wires, and quantum dots (see, for example, [1][2][3][4][5][6] and literature thereto), a large number of both experimental and theoretical works have been devoted to studying the properties of so-called semiconductor nanoplatelets (NPLs) in the last decade [7][8][9][10][11]. NPLs are planar quasi-two-dimensional (quasi-2D) structures with pronounced charge carrier size quantization in the direction perpendicular to the sample plane, as well as the presence of organic environment and lateral confinement [7][8][9][10][11].…”

This paper theoretically studies the impurity states and the effect of impurity concentration and configuration on the optical, electrical, and statistical properties of CdSe nanoplatelets (NPLs). The image charge-based model of electron–impurity interaction has been proposed. The charge carrier energy spectra and corresponding wave functions depending on impurity number and configuration have been calculated. The electron binding energies have been calculated for different NPL thicknesses. It has been shown that the image charges-based interaction potential that arises due to the dielectric constants mismatch is much stronger than the interaction potential that does not take such a mismatch into account. Also, it has been demonstrated that binding energies are increasing with the number of impurities. We calculated the canonical partition function using the energy levels of the electron, which in turn is used to obtain the mean energy, heat capacity, and entropy of the noninteracting electron gas. The thermodynamic properties of the noninteracting electron gas depending on the geometric parameters of the NPL, impurity number, configuration, and temperature have been studied.

Optical frequency combs (OFCs) have evolved into one of the most active areas of photonics, underpinning advancements in both fundamental science and commercial contexts. Electro‐optic modulation for OFC generation offers excellent versatility, stability, and phase coherence. With the rapid progress in micro‐nano fabrication techniques, electro‐optic frequency combs (EOFCs) have been realized on many integrated platforms, including silicon on insulator (SOI), indium phosphide (InP), and lithium niobate on insulator (LNOI). These compact, low‐cost, and energy‐efficient EOFCs support a wide range of applications. In this study, we review the theory for the generation of integrated EOFCs, summarize the demonstrations on the main integrated platforms, present applications, and envision the development directions of integrated EOFCs in view of materials, devices, and applications.
