Heavy Fermions to the Scheme from Semimetals

B. Goswami


This article is a study about heavy Fermions to scope strange and unknown features of scattering accounted to conduction electrons in the metal. Nucleons generated by heavy metal compounds are named heavy fermions. These generate from magnetic impurities that are present in the matter as unusual distribution in particulate forms. Parameter of quasi-crystal lattice instability of these compounds has significance in response to behave as non-Fermi liquids affected under magneto-transport. Super conduction transition has an anomaly in resistivity variation under different range based scopes. The metamaterial is brought under the scope of electromagnetic meta-surface design at nano-scale from the behavioural synergism of earlier natural material. Kondo-holes described the creation of intense nanoscale heavy-fermion hybridization disorder. On the other hand, power generation and solid-state cooling is the ability of thermoelectric (TE) materials aligned as vice-versa transformation of heat to electricity. Cryogenic thermoelectric devices are useful for the aerospace program underweight and size margins. 2D boron nitride (BN) monolayers made of five- and seven-membered rings or 5–7 BN structure and next layer of Kagome lattice exhibited interesting electronic properties by first-principles calculations. 5–7 BN is a Dirac semimetal, whose conduction and valence bands cross on Fermi level and thus form Dirac points. Two flat bands existed below Fermi level by Kagome BN to generate heavy fermions and thus, strongly correlated effect between fermions. After one-hole doping, Kagome BN became half metal because flat band splits to spin-up and spin down bands. Matter synthesis linked to 5–7 BN on PbO2 (111) substrate and Kagome BN on CdO (111) substrate. Both showed unusual electronic properties.
