Energy filtering of charge carriers is directed toward enhancing the material thermopower. This paper focuses on the theoretical concepts, experimental evidence, and the authors' view of energy filtering in the context of thermoelectric materials. Recent studies suggest that not all materials experience ...
In this Perspective, we discuss recent work in the emerging field of hybrid plasmonics. We focus on fundamental questions related to the nanoscopic flow of energy and excited charge carriers in these multicomponent materials. We also address critical misconceptions, challenges and opportunities that ...
It is a challenge to extract the energy sensitivity of charge carriers’ transport and scattering from experimental data, although a theoretical estimation in which the existing scattering mechanism(s) are preliminarily assumed can be easily done. To tackle this problem, we have developed a method t...
2b). This remarkable difference has been explained based on the higher conductivity of graphene films: on one hand, graphene films have higher concentration of charge carriers, whereas only one third of nanotubes are metallic; on the other hand, graphene is a continuous film with semimetal ...
The nonradiative recombination of charge carriers at the hole transport layer (HTL)/perovskite interface generally induces remarkable performance loss of the inverted two-dimensional perovskite solar cells (2D PSCs). Herein, a cross-linkable small molecule of 2-mercaptoimidazole (2-MI) was introduced...
The estimation of state of charge (SOC) using deep neural networks (DNN) generally requires a consider-able number of labelled samples for training, which refer to the current and voltage pieces with knowing their corresponding SOCs. However, the collection of labelled samples is costly and time...
Figure 1.(a) The structure of crystalline silicon solar cell, the typical solar cell in use today. The bulk of the cell is formed by a thick p-type base in which most of the incident light is absorbed and most power is generated. After light absorption, the minority carriers (electrons...
Kinetic energy driven superconductivity, the origin of the Meissner effect, and the reductionist frontier Is superconductivity associated with a lowering or an increase of the kineticenergy of the charge carriers? Conventional BCS theory predicts that thekineti... HIRSCH,E J. - 《International Journal...
and vibrational degrees of freedom13,14and it was broadly hypothesized that oscillatory evolution of delocalized electronic wavefunctions can improve transport of energy and charge carriers for light-harvesting, lighting, and other optoelectronic applications1,3,8,15,16. The change in thinking towards ...
Seawater electrolytes provide a sustainable option for aqueous zinc batteries but challenge the stability of zinc metal electrodes. Here, authors elucidate the zinc electrode failure mechanisms and propose a charge gradient interface strategy to stabilize the zinc electrode in seawater electrolytes. ...
