Abstract The electron-doped cuprate superconductor exhibits a unique electronic structure, where both electron and hole Fermi surface (FS) pockets coexist in the optimally doped (OP) region, while in the overdoped (OD) region there exists only a large hole FS pocket. It is therefore an intriguing question whether or not a p-n junction arises if the OD electron-doped cuprate interfaces with the OP compound. Here, we construct such an in-plane junction by selectively modulating the doping levels in thin films of ${\mathrm{La}}_{2-x}{\mathrm{Ce}}_{x}\mathrm{Cu}\mathrm{O}_{\mathrm{4}}$ (LCCO) — a typical electron-doped cuprate. We find that the junction exhibits non-linear, asymmetric $I$-$V$ characteristics, which are consistent with those of a p-n semiconductor junction, across a wide temperature range from 250 K to 10 K, regardless of the Hall coefficient sign change or the superconducting transition. We attribute these features to a potential barrier formed at the junction, which is set by the band bending in both OD and OP LCCO.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
