Fermi level engineering of metallicity-sorted metallic single-walled carbon nanotubes by encapsulation of few-atom-thick crystals of silver chloride

Structure of inorganic nanocrystals confined within carbon nanotubes

“…As a consequence of the crystal-CNT interaction, the electronic structure of carbon nanotubes suffers significant alterations. In order to determine filling induced changes in the electronic properties of the hosting SWCNT Kharlamova et al evaluated both pristine (metallic) and AgCl@SWCNTs using Raman spectroscopy [56]. Variations in the RBM band of filled CNTs when compared to their empty counterparts suggest changes in the resonance excitation conditions due to deformations of the cross section of the host.…”

“…CNTs provide by themselves interesting characteristics to the new synthesized hybrids. Variations in the mechanical properties or induced electrical doping have been reported due to the interaction of both hosting nanotubes and inorganic crystals [56]. Thus, understanding the mechanisms of growth and interactions of the atoms from the encapsulated nanostructure with the conjugated lattice of the nanotubes is essential to develop new protocols for obtaining materials with specific properties and expanding the range of applications.…”

Synthesis and Properties of Single-Walled Carbon Nanotubes Filled with Metal Halogenides and Metallocenes

“…In the literature, there are the reports on the investigation of the electronic properties of SWCNTs filled with MnCl 2 , MnBr 2 [45,46], FeCl 2 , FeBr 2 , FeI 2 [47], CoBr 2 [48], NiCl 2 [49], NiBr 2 [49,50], CuCl [51,52], CuBr [51], CuI [51,53,54], ZnCl 2 [55,56], ZnBr 2 , ZnI 2 [55], RbI, RbAg 4 I 5 [57], AgCl [58][59][60][61], AgBr, AgI [58], CdCl 2 [56,62,63], CdBr 2 , CdI 2 [62], SnF 2 [64], TbCl 3 [56,65,66], TbBr 3 , TbI 3 [66], PrCl 3 [65,67], ErCl 3 [68], TmCl 3 [65,69], and HgCl 2 [70]. The characterization of the electronic properties of the filled SWCNTs was performed by three main techniques: OAS, Raman spectroscopy, and XPS.…”

“…These modifications are common for metal halogenide-filled SWCNTs. They were reported for SWCNTs filled with MnCl 2 , MnBr 2 [45,46], FeCl 2 , FeBr 2 , FeI 2 [47], CoBr 2 [48], [57], TbCl 3 [56,65,66], TbBr 3 , TbI 3 [66], TmCl 3 [65,69], PrCl 3 [65,67], AgCl [58][59][60][61], AgBr, AgI [58], and HgCl 2 [70].…”

“…The latter method is especially promising, because a variety of substances with different properties can be encapsulated inside SWCNTs. The filling of SWCNTs with fullerene C 60 [14] and RuCl 3 [15] was firstly performed in 1998 and since then the topic has attracted increasing attention. SWCNTs were filled with different simple elemental substances, metals [16][17][18][19][20][21][22] and nonmetals [17,23], chemical compounds, metal halogenides [24][25][26][27][28][29], metal chalcogenides [30][31][32][33][34] and metal oxides [35,36] as well as molecules, fullerenes and their derivatives [37][38][39][40][41] and metallocenes [42,43].…”
