Anomalous caustics and Veselago focusing in 8-Pmmn borophene p–n junctions with arbitrary junction directions
Negative refraction usually demands complex structure engineering while it is very natural for massless Dirac fermions (MDFs) across the p–n junction (PNJ), this leads to Dirac electron optics. The emergent Dirac materials may exhibit hitherto unidentified phenomenon due to their nontrivial band str...
