Some Important Contributions

In chronological order:

  • Determined the superconducting energy gap from measurements of the superconducting penetration depth in the "classic" superconductors tin and lead.
      "Observations of the Energy Gap by Low Temperature Penetration Depth Measurements in Lead," Phys. Rev. Lett. 4: 52 (1960), with R.L. Garwin and E. Erlbach.
      "Measurement of Magnetic Field Attenuation by Thin Superconducting Films," IBM Journal of Research and Development 4: 107 (1960), with E. Erlbach and R.L. Garwin.
  • Established the correspondence between a minimum in the electrical resistivity of an alloy as a function of temperature and the presence of dilute magnetic moments. This work played a key experimental role in support of the theoretical advance embodied in the Kondo effect.
      "Resistivity of Mo-Nb and Mo-Re Alloys Containing 1% Fe," Phys. Rev., 135A: 1041 (1964), with E. Corenzwit and L.D. Longinotti.
  • Measurements of the effect of a magnetic field on the electrical conductivity of doped semiconductors near the metal-insulator transition showed that application of a magnetic field changes the universality of the transition.
      "Electrical Conductivity of Metallic Si:B near the Metal- Insulator Transition," Phys. Rev. B45: 3984 (1992), with Peihua Dai and Youzhu Zhang.
      "The Critical Conductivity Exponent of Si:P in a Magnetic Fields," Phys. Rev. (Rapid Communications) B48: 4941 (1993), with Peihua Dai, Youzhu Zhang, and Snezana Bogdanovich.
  • Established that the Hall coefficient diverges at the metal-insulator transition in doped silicon.
      "Critical Behavior of the Hall Coefficient of Si:P at the Metal-Insulator Transition," Phys. Rev. (Rapid Communication) B49: 14039 (1994), with Peihua Dai and Youzhu Zhang.
  • Measurements of the nonlinear electric field response in a two-dimensional electron gas showed a conductivity/resistivity reflection scaling across the metal-insulator transition.
      "Electric Field Scaling at a B=0 Metal-Insulator Transition in Two Dimensions," Phys. Rev. Lett. 77: 4938 (1996), with S. V. Kravchenko, D. Simonian, Whitney Mason, and J. Furneaux.
  • Discovered steps in the hysteresis loop of a magnetic molecular crystal that showed macroscopic quantum tunneling in a large spin system.
      "Macroscopic Measurement of Magnetization Tunneling in High-Spin Molecules," Phys. Rev. Lett.76: 3830 (1996), with Jonathan R. Friedman, J. Tejada, and R. Ziolo.
