Synergetic enhancement of power factor and suppression of lattice thermal conductivity via electronic structure modification and nanostructuring on Ni and B co-doped p-type Si-Ge alloy
Muthusamy Omprakash, Saurabh Singh, Keisuke Hirata +7
For simultaneously achieving the high-power factor and low lattice thermal conductivity of Si-Ge based thermoelectric materials, we employed, in this study, constructively modifyin…
First-principles calculations of thermal electron emission from H in silicon
Yoshiyuki Yamamoto, Alpin Novianus Tatan, Osamu Sugino
Thermal electron emission process of a hydrogen impurity is an important topic of fundamental semiconductor physics. Despite of decades-long study, theory is not established yet. H…
Distinctive Thermoelectric Properties of Supersaturated Si-Ge-P Compounds: Achieving Figure of Merit ZT > 3.6
Swapnil Ghodke, Omprakash Muthusamy, Kevin Delime Codrin +9
The efficiency of energy conversion in thermoelectric generators (TEGs) is directly proportional to electrical conductivity and Seebeck coefficient while inversely to thermal condu…
Iterative diagonalization of the non-Hermitian transcorrelated Hamiltonian using a plane-wave basis set: Application to -electron systems with deep core states
Masayuki Ochi, Yoshiyuki Yamamoto, Ryotaro Arita +1
We develop an iterative diagonalization scheme in solving a one-body self-consistent-field equation in the transcorrelated (TC) method using a plane-wave basis set. Non-Hermiticity…
Intrinsic mechanism for high temperature ferromagnetism in GaMnN
Saki Sonoda, Isao Tanaka, Hidekazu Ikeno +9
Considerable efforts have been devoted recently to synthesize diluted magnetic semiconductors having ferromagnetic properties at room temperature because of their technological imp…
