Query: Quantized Thermoelectric Hall Effect Induces Giant Power Factor in a
  Topological Semimetal   Thermoelectrics are promising by directly generating electricity from waste
heat. However, (sub-)room-temperature thermoelectrics have been a long-standing
challenge due to vanishing electronic entropy at low temperatures. Topological
materials offer a new avenue for energy harvesting applications. Recent
theories predicted that topological semimetals at the quantum limit can lead to
a large, non-saturating thermopower and a quantized thermoelectric Hall
conductivity approaching a universal value. Here, we experimentally demonstrate
the non-saturating thermopower and quantized thermoelectric Hall effect in the
topological Weyl semimetal (WSM) tantalum phosphide (TaP). An ultrahigh
longitudinal thermopower Sxx= 1.1x10^3 muV/K and giant power factor ~525
muW/cm/K^2 are observed at ~40K, which is largely attributed to the quantized
thermoelectric Hall effect. Our work highlights the unique quantized
thermoelectric Hall effect realized in a WSM toward low-temperature energy
harvesting applications.
