WebMar 30, 2024 · We measured Hall bar devices of ion-exchange doped films of PBTTT-C 14 from 10–300 K. Our analysis provides evidence for the proportion of conductivity arising from deflectable transport, d (T), increasing with doping level, ranging between 15.4% and 16.4% at room temperature. WebJun 27, 2014 · The electronic structure of the two-dimensional material MoS 2 has two distinct “valleys” of energy that may help to carry information in future electronic devices. Mak et al. observed the so-called valley Hall effect in a monolayer of MoS 2.The electrons from different valleys moved in opposite directions across the sample, with one valley …

Resistivity and Hall Measurements NIST

A Hall effect sensor (or simply Hall sensor) is a type of sensor which detects the presence and magnitude of a magnetic field using the Hall effect. The output voltage of a Hall sensor is directly proportional to the strength of the field. It is named for the American physicist Edwin Hall. Hall sensors are used for proximity sensing, positioning, speed detection, and c… WebJun 26, 2013 · Figure 1: Characterization of Bi 2 Se 3 Hall bar devices.
