Semiconductor Physics (49) – Surface Conductivity and Mobility

Semiconductor Physics (49) - Surface Conductivity and Mobility

(1) The greater the number of carriers and mobility in the semiconductor surface layer, the greater the surface conductivity. The number of carriers in the surface layer will change with the surface potential Vₛ, thus changing the surface conductivity. (2) Due to the effect of the surface electric field, additional hole number Δp and electron … Read more

Installing Pi-hole on OpenWrt Router (NanoPi R5C) for Ad Filtering and DNS Caching

Installing Pi-hole on OpenWrt Router (NanoPi R5C) for Ad Filtering and DNS Caching

NO.1 Pi Hole Note: This Pi Hole deployment on OpenWrt was successful, but it failed to work. DNS filtering only works within OpenWrt, and there is no data reflected on other clients. Therefore, after this deployment, the R5C will prioritize resolving the wireless card issue, and other plugins and Docker applications will be postponed. I … Read more
