This work is an extension of previous analysis of high-field, hot-electron noise in n-type germanium. The previous analysis, developed to explain the author's observations of field-direction (longitudinal) noise, is extended here in an attempt to explain the hot-electron, transverse noise observations of Erlbach and Gunn.In the model adopted, the transverse current fluctuations, resulting from intravalley and intervalley scattering, within the interelectrode volume (electrode area × separation), yield both thermal and intervalley contributions to the noise temperature. For two of the three crystal orientations considered, the intervalley noise is negligible, but in the third case, the two contributions are of the same order.Individual valley currents, populations, and relative intervalley transition rates are calculated from Nathan's analysis, and the Barrie–Burgess theory of high-field transport provides the valley electron temperatures. The intervalley scattering data of Weinreich, Sanders, and White yield absolute values of the intervalley scattering probabilities.Poor agreement is found with the Erlbach–Gunn observations of transverse noise temperature, which may be due to the shunting effect of the portion of the sample exterior to the interelectrode volume.

Abstract Hot electrons generated in metallic nanostructures have shown promising perspectives for photodetection. This has prompted efforts to enhance the absorption of photons by metals. However, most strategies require fine-tuning of the geometric parameters to achieve perfect absorption, accompanied by the demanding fabrications. Here, we theoretically propose a Ag grating/TiO2 cladding hybrid structure for hot electron photodetection (HEPD) by combining quasi-bound states in the continuum (BIC) and plasmonic hot electrons. Enabled by quasi-BIC, perfect absorption can be readily achieved and it is robust against the change of several structural parameters due to the topological nature of BIC. Also, we show that the guided mode can be folded into the light cone by introducing a disturbance to become a guided resonance, which then gives rise to a narrow-band HEPD that is difficult to be achieved in the high loss gold plasmonics. Combining the quasi-BIC and the guided resonance, we also realize a multiband HEPD with near-perfect absorption. Our work suggests new routes to enhance the light-harvesting in plasmonic nanosystems.
