Carbon Oxide Decomposition as a Novel Technique for Ultrahigh Quality ZnO Nanowire Crystallization

By modifying the classic method of growing ZnO nanowires, we were able to achieve an exceptionally high level of structural and optical quality in individual ZnO nanowires. The half-width of the exciton bound to the donor measured an unprecedented...

Charge dopants control quantum spin Hall materials

Unlike in the quantum Hall effect and quantum anomalous Hall effect, the quantization precision in the quantum spin Hall effect depends on unavoidable background impurities and defects. However, doping with magnetic ions restores the quantization ...

Materiały topologiczne a granice miniaturyzacji elektronicznej

Postępująca w zawrotnym tempie miniaturyzacja nanoukładów elektronicznych wymaga nowych rozwiązań także w zakresie ultra cienkich połączeń galwanicznych, np. z wykorzystaniem 10-20 nanometrowej szerokości ścieżek metalicznych z miedzi lub złota.
