Figure 1: Schematic of TI surface bands and experimental concept. Transport measurements were also performed with the applied field and detector contact magnetization parallel/antiparallel to the ...

In a metal like copper, however, the outer electrons swim around freely and are shared by all the atoms. That’s why ...

This Design Idea describes a method by which you can detect and assess air or liquid fluid flow using an externally heated semiconductor diode. Airflow across the heated diode reduces its temperature, ...
