“…It has been found in recent years that doping diamond, Si and Ge with holes gives rise to superconductivity [35]. This is consistent with the theory of hole superconductivity, as is the fact that superconductivity is not found when these semiconductors are doped with electrons.…”

The theory of hole superconductivity proposes that there is a single mechanism of superconductivity that applies to all superconducting materials. This paper discusses several material families where superconductivity occurs and how they can be understood within this theory. Materials discussed include the elements, transition metal alloys, high $T_c$ cuprates both hole-doped and electron-doped, $MgB_2$, iron pnictides, doped semiconductors, and elements under high pressure.Comment: published version, small changes from v

“…However, Aluminum and Gallium being superconducting elementary metals with respective TC of 1.2K and 1.1 K, the authors have considered the possibility that the superconductivity originated from Al or Ga clusters. They have so far concluded that Ga-rich amorphous nano-inclusions are present only in the case 71 of Si:Ga. As explained in a recent summarizing overview 72 , such caveats apply to any compound containing one element (for instance Pb, In or Ga) which may form a superconducting island. This is the reason why except for the specific case of PbTe 73 , the numerous reports about PbSe, InN and In2O3, or GaAs and GaN, despite their quality, will not be mentioned in this review.…”

International audienceA historical survey of the main normal and superconducting state properties of several semiconductors doped into superconductivity is proposed. This class of materials includes selenides, tellurides, oxides and column-IV semiconductors. Most of the experimental data point to a weak coupling pairing mechanism, probably phonon-mediated in the case of diamond, but probably not in the case of strontium titanate, these being the most intensively studied materials over the last decade. Despite promising theoretical predictions based on a conventional mechanism, the occurrence of critical temperatures significantly higher than 10 K has not been yet verified. However, the class provides an enticing playground for testing theories and devices alike

“…Just to give some factual proof of increased popularity of superconductivity in diamond and related materials, regular international conferences dedicated to this topic are being held [13,14], and the number of related papers has risen dramatically [15].…”

Abstract:This review covers recent advances in superconductivity of diamond, Si, SiC, group III-V and II-IV semiconductors, metal-intercalated graphite and fullerites. The results are critically analyzed and prospects are given for future research directions. In particular, it is argued that the highest transition temperatures of ∼9 K in diamond and 11.5 K in CaC 6 can further be enhanced and that no reliable evidence exists yet for superconductivity in III-V semiconductors.PACS (2008)
