The six-phase twisted-ring counter circuit

2004 24th International Conference on Microelectronics (IEEE Cat. No.04TH8716), 2004
The behavior of the Six-Phase Twisted-Ring Counter (6P-TRC) circuit is analyzed. The circuit demultiplexes the input signal into six individual phased clock signals that exercise a phase difference equal to the half period of the clock. A tree-like structure is built by applying the phased outputs of the circuit to the clock inputs of six replicas of ...

Nematic twist-bend phase under external constraints

Liquid Crystals, 2016
ABSTRACTThe recently discovered twist-bend nematic phase, NTB, has short-pitched heliconical structure with doubly degenerate handedness. In contrast to the classic nematic, in the NTB phase the director is spontaneously distorted, resulting in unusual elastic properties.

Nematic Twist-Bend Phases of Liquid Crystals

2017
Banana-shaped molecules are mesogenic molecules that are able to form liquid crystal phases. The onset of interest in such molecules was spurred by the hope of obtaining biaxial nematic phases. Instead of the expected biaxial phase, another phase has been found.

Z2topological phase transition in twisted plumbene.

Journal of physics. Condensed matter : an Institute of Physics journal
Since the discovery of superconductivity in twisted bilayer graphene, which initiated the field of twistronics, Moiré patterns caused by different twisting angles between stacked layers of van der Waals 2D materials show unique properties in these structures.
