Areas of Expertise

  • Transport of heat, charge and spin in solids
  • Thermoelectricity, thermodynamics
  • Physics of narrow-gap semiconductors


Research interests

Experimental investigation of electron, phonon and spin transport properties, semiconductor, semimetals, topological and magnetic materials and nanostructures. Contributions:

  • Phonon physics. Phonons in ferroelectric materials are affected by an external electric field.  This opens the field of study of mixed polarization and heat transport, polarization caloritronics. Phonon transport is also modulated by a magnetic field in diamagnets.
  • Goniopolar materials exhibit simultaneous n- and p-type behavior by the same charge carriers.  They enable the construction of transverse thermoelectric generators that have no electrical contacts at their hot side, and mostly eliminate efficiency losses in contact resistances.
  • Thermal properties of electrons in topological and quantum materials.  The gravitational anomaly (or thermal chiral anomaly) is a new way for electrons to carry heat in Weyl semimetals, in which electrons are massless but chiral.
  • Mixed heat and spin transport, spin caloritronics: The spin-Seebeck effect in magnetic and narrow-gap semiconductors, and the magnon-drag effect in metals and semiconductors.
  • Thermoelectricity.
    • Resonant dopants increase the thermoelectric figure of merit.
    • Large thermopowers in quantum wires due to size-quantization.
  • Geometrical effects in the transport of heat and charge in narrow-gap semiconductors, commercialized in magnetic position sensors used on crank and camshafts by General Motors.
