DOI: 10.1088/1361-6463/ad94fe
Abstract: Studies of quintuple layers (QLs) dependent transport can shed light on the bulk and surface states because bulk and surface transport parameters have different QL dependencies. The QL dependency of material properties in Bi2Se3 reported… read more here.

DOI: 10.1088/1361-6528/ad8098
Abstract: Two-dimensional topological insulators (TIs) show great potential applications in low-power quantum computing and spintronics due to the spin-polarized gapless edge states. However, the small bandgap limits their room-temperature applications. Based on first-principles calculations, a series… read more here.

DOI: 10.1103/physrevb.103.094307
Abstract: We study the possibility of transferring fermions from a trivial system as particle source to an empty system but at topological phase as a mold for casting a stable topological insulator dynamically. We show that… read more here.

DOI: 10.1103/physrevlett.121.213902
Abstract: We reveal a one-dimensional topological insulating phase induced solely by gain and loss control in non-Hermitian optical lattices. The system comprises units of four uniformly coupled cavities, where the successive two have loss; the others… read more here.
