High thermoelectric power factor in Ni-Fe alloy for active cooling applications
Shuai Li, Sree Sourav Das, Haobo Wang +5
Metallic thermoelectric materials are promising candidates for active cooling applications, where high thermal conductivity and a high thermoelectric power factor are essential to…
3D Nanostructures on Ge/Si(100) Wetting Layers: Hillocks and Pre-Quantum Dots
Gopalakrishnan Ramalingam, Jerrold A. Floro, Petra Reinke
The annealing of sub-critical Ge wetting layers (WL<3.5 ML) initiates the formation of 3D nanostructures, whose shape and orientation is determined by the WL thickness and thus dir…
Mn Solid Solutions in Self-Assembled Ge/Si (001) Quantum Dot Heterostructures
Joseph Kassim, Christopher Nolph, Matthieu Jamet +2
Heteroepitaxial Ge0.98Mn0.02 quantum dots on Si (001) were grown by molecular beam epitaxy. The standard Ge wetting layer-hut-dome-superdome sequence was observed, with no indicato…
Surface Driven Mn-Doping of Ge Quantum Dots - Mn-Interaction with the Ge QD{105} Facet and the Wetting Layer
C. A. Nolph. J. K. Kassim, J. A. Floro, P. Reinke
The interaction of Mn with Ge quantum dots (QD), which are bounded by {105} facets, and the strained Ge wetting layer (WL), terminated by a (001) surface, is investigated with scan…
Mechanisms for directed self-assembly of heteroepitaxial Ge/Si quantum dots with deterministic placement and sub-23nm spacing on SiC nanotemplates
Christopher W. Petz, Dongyue Yang, Jeremy Levy +1
Artificially ordered Ge quantum dot (QD) arrays, where confined carriers can interact via exchange coupling, may create unique functionalities such as cluster qubits and spintronic…
Inhomogeneous low temperature epitaxial breakdown during Si overgrowth of GeSi quantum dots
Christopher W. Petz, Jerrold A. Floro
Low temperature epitaxial breakdown of inhomogeneously strained Si capping layers is investigated. By growing Si films on coherently strained GeSi quantum dot surfaces, we differen…
