A room-temperature ferroelectric semimetal was published in Science Advances in July 2019.
Graphene is a zero-bandgap semimetal, of which the valence band and conduction band meet at the Dirac points.
In order to improve the thermoelectric performance of [Bi.sub.2][Te.sub.3]-based thermoelectric materials, another effective way is to incorporate semimetal into the base thermoelectric materials.
Bismuth (Bi), as a fantastic p-block semimetal with highly anisotropic Fermi surface, small effective electron mass, low carrier density, and long carrier mean-free path [20-23], is conventionally deemed as a sound candidate to observe and investigate quantum confinement and finitesize effects, enhanced magnetoresistance, and thermoelectricity [21, 22, 24, 25].
Graphene is nearly a transparent, twodimensional semimetal consisting of a single atomic lattice of hexagonally arranged sp2 hybridized carbon atoms [1].
Near the WTI-STI transition, there emerges a novel Weyl semimetal phase, in which the Fermi arcs generically appear at both cleavage surfaces, whereas the Fermi circle only appears at one selected surface.
By housing Weyl fermions, tantalum arsenide becomes the first experimentally confirmed Weyl semimetal, a metal-like material with exotic and potentially useful features.
In the research by Towat with the article "Analyzing the semimetal of patients with unsuccessful suicide in referring to Pelonomi Hospital and the analyze of mentality and treatment from May to April 2006 the results indicated that most of the patients (68.9%) of patients were women that their average age was 22.
Opposed to the case of single- and bilayer, the trilayer material is a semimetal with a gate tuneable band overlap between the conduction and the valence bands [16].
