Bosonic Spectral Function and the Electron-Phonon Interaction in HTSC Cuprates

Figure 32

(a) Typical conductance 𝑑𝐼/𝑑𝑉(𝐫,𝐸). The ubiquitous features at eV>Δ(gap) with maximal slopes, which give peaks in 𝑑²𝐼/𝑑𝑉²(𝐫,𝐸), are indicated by arrows. (b) The histograms of all values of Ω(𝐫) for samples with O¹⁶—right curve and with O¹⁸—left curve. From [61–63].
