Inelastic electron tunneling spectroscopy (IETS) played a central
role in
determining that phonons were responsible for conventional
superconductivity[1]. Since STM-based IETS can reveal local
vibrational
modes[2], and STM-based Fourier transform scanning tunneling
spectroscopy
(FT-STS) [3] can reveal momentum-space structure of elastic
scattering
processes[4], a combination of these techniques might be used to
elucidate
the momentum-space structure of electron-boson inelastic
processes in
cuprates[5]. Here we introduce this new STM technique, FT-IETS,
in which we
map the derivative of the differential conductance,
d$^{2}$I/dV$^{2}$, with
atomic resolution in the high-T$_{c}$ superconductor
Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8+\delta {\rm g}}$. Fourier
analysis is then
used to search for the momentum-space structure of electron-boson
interactions in this system [6].
