On the interplay of paramagnetism and topology in the Fe-based High Tc Superconductors
J. D. Rameau, N. Zaki, G. D. Gu +2
The high Tc superconductor FeTe0.55Se0.45 has recently been shown to support a surface state with topological character. Here we use low-energy laser-based ARPES with variable ligh…
The cuprate phase diagram and the influence of nanoscale inhomogeneities
Nader Zaki, Hongbo Yang, Jon Rameau +3
The phase diagram associated with the high Tc superconductors is complicated by an array of different ground states. The parent material represents an antiferromagnetic insulator b…
Universal scaling of length, time, and energy for cuprate superconductors based on photoemission measurements of Bi2Sr2CaCu2O8+δ
J. D. Rameau, Z. -H. Pan, H. -B. Yang +2
A microscopic scaling relation linking the normal and superconducting states of the cuprates in the presence of a pseudogap is presented using angle-resolved photoemission spectros…
On the Properties of Hydrogen Terminated Diamond as a Photocathode
Jonathan Rameau, John Smedley, Eric Muller +2
Electron emission from the negative electron affinity (NEA) surface of hydrogen terminated, boron doped diamond in the [100] orientation is investigated using angle resolved photoe…
On the Reconstructed Fermi Surface in the Underdoped Cuprates
H. -B. Yang, J. D. Rameau, Z. -H. Pan +5
The Fermi surface topologies of underdoped samples the high-Tc superconductor Bi2212 have been measured with angle resolved photoemission. By examining thermally excited states abo…
Coupling of Low Energy Electrons in Optimally Doped Bi2212 to an Optical Phonon Mode
J. D. Rameau, H. -B. Yang, G. D. Gu +1
Laser based photoemission with photons of energy 6 eV is used to examine the fine details of the very low energy electron dispersion and associated dynamics in the nodal region of…
