Abstract: Single‐element polarization in low dimensions is fascinating for constructing next‐generation nanoelectronics with multiple functionalities, yet remains difficult to access with satisfactory performance. Here, spectroscopic evidences are presented for the spontaneous electronic polarization in tellurium (Te)… read more here.

Abstract: Abstract The structural evolution of nano Cu-precipitates was studied with high-resolution transmission electron microscopy. 9R Cu precipitates were mainly multiple-twinned. However, the unusual 9R Cu precipitates with no twins were also observed. The 9R→face-centered tetragonal… read more here.
