5.2B. The detectors operate by free-carrier absorption, followed by internal photoemission of the excited carriers and sweep out of the emitted carriers by an externally applied electric field. Because the work
Free charge carriers in MoSe2 can interact with X0 by introducing additional scattering, which leads to the broadening of X0 (refs. 20,21). The features I, II and IV are defined in the same way as in Fig. 2. Along the nt:nb = 1:1 and 4:1 features (I and II), we observe ...
Here, we report on the colloidal synthesis of direct bandgap GaP quantum shells (QSs) on the surface of a ZnS core with a reverse-type I structure, in which generated charge carriers are confined within the shell. We discovered that the ZnS nanocrystal (NC) template plays a crucial role in...
solvents and crystal structures, etc., which are not taken into account in the above two theories. Currently, Pearson’s hard and soft acid base theory is widely used for assessing the affinity between metal ions and ligands/solvents [64]. It offers a framework to ...
Because the reflectance and PL from X0 depend sensitively on the pres- ence of free carriers in the system20,21,24–26, the increased intensity of X0 indicates that unexpected insulating states are formed at these specific density ratios, even though both layers are e...
(OVHE) where opposite spin carriers propagate in different directions. While the OVHE has been observed in TMD ML and BLs, the extent of the effect is limited by the exciton valley polarization lifetime, which has shown decay times of\(\sim10s\,\text{ps}\)at cryogenic temperatures due ...
In order to assess the ultrafast dynamics of the photoinduced electronic transition, we use time-resolved photoemission experiments which provide direct insight into the dynamics of electronic structure and charge carriers. First, the low- and high-temperature phase are characterized in thermodynamic equil...
Precise control from the bottom-up for realizing tunable functionality is of utmost importance to facilitate the development of molecular electronic devices. Until now, however, manipulating charge carriers over single-molecule scale remains intractable.
Voltages applied to the top-gate (VTG) predominantly control the density of carriers confined close to the interface, but the electronic thickness remains nearly constant (Fig. 1b). When VTG is decreased, the overall scattering is reduced due to the decrease of carriers distributed close to the...
If such is the case, it is within the scope of the present invention that such instructions may be stored on one or more processor readable carriers (e.g., a magnetic disk), or transmitted to one or more processors via one or more signals. The present invention is not to be limited ...
