Room-temperature chemical synthesis of C2

Nature Communications, 2020
Diatomic carbon (C2) is historically an elusive chemical species, considered to require high physical energy for its generation. Here, the authors describe the first room-temperature chemical synthesis of C2 and present experimental evidence for its ...

Room-Temperature Quantum Transport Phenomenon in Low-Temperature-Grown Zn_1–xMg_xO/ZnO Heterostructures

, 2020
Quantum transport phenomenon such as quantum Hall effect usually appears up at cryogenic temperature. Here, we observe a room-temperature quantum transport phenomenon in ZnO-based two-dimensional systems.

Bloch oscillations at room temperature [PDF]

Physical Review B, 1995
We report on the observation of coherent electronic wave-packet oscillations in a semiconductor heterostructure at room temperature. Bloch oscillations are excited in a wide-miniband GaAs/${\mathrm{Al}}_{0.3}$${\mathrm{Ga}}_{0.7}$As superlattice by femtosecond laser pulses.
