We have measured the thermoelectric power and resistivity of the 120 K superconductor HgBa2CaCu2Oe+s (Hg-1212) as a function of temperature and oxygen annealing. Before annealina the Seebeck coefficient is moderate and positive, sugletting that the as-grown compound is slightly under-doped. After an
We have developed a technique to measure the thermopower of a mesoscopic device. Absolute calibration is possible, and we ΓΏnd that a constriction in a 2D electron gas obeys theoretical predictions su ciently well that its thermopower can be used for electron thermometry. This has been applied to mea
