Journal ArticleDOI
Electrical Nanocharacterization of Epitaxial Graphene/Silicon Carbide Schottky Contacts
Filippo Giannazzo,Stefan Hertel,Andreas Albert,Antonino La Magna,Fabrizio Roccaforte,Michael Krieger,Heiko B. Weber +6 more
TL;DR: In this paper, a quasi-freestanding graphene formed a Schottky contact to n-type SiC with a barrier height of 1.5 eV as determined from C-V analysis and core level photoelectron spectroscopy (XPS).
Journal ArticleDOI
Z1/2- and EH6-Center in 4H-SiC: Not Identical Defects ?
Bernd Zippelius,Alexander Glas,Heiko B. Weber,Gerhard Pensl,Tsunenobu Kimoto,Michael Krieger +5 more
TL;DR: In this article, the activation energy of EH6 (EC - ET(EH6) = 1.203 eV) turns out to be independent of the electric field, and EH7 is acceptor-like according to the missing Poole-Frenkel effect.
Journal ArticleDOI
Reduction of Density of 4H-SiC / SiO2 Interface Traps by Pre-Oxidation Phosphorus Implantation
Tomasz Sledziewski,Aleksey I. Mikhaylov,Sergey A. Reshanov,Adolf Schöner,Heiko B. Weber,Michael Krieger +5 more
TL;DR: The effect of phosphorus (P) on the electrical properties of the 4H-SiC/SiO2 interface was investigated in this article, where P+-implanted samples with [P]interface = 1.5 1018 cm-3 in the SiC layer at the interface.
Journal ArticleDOI
Covalent Patterning of 2D MoS2
Xin Chen,Malte Kohring,Mhamed Assebban,Bartlomiej Tywoniuk,Cian Bartlam,Narine Moses Badlyan,Janina Maultzsch,Georg S. Duesberg,Heiko B. Weber,Kathrin C. Knirsch,Andreas Hirsch +10 more
TL;DR: In this article, the authors demonstrate a patterning strategy by combining the electron beam lithography with surface covalent functionalization, which allows to generate delicate MoS2 ribbon patterns with a minimum feature size of 2 m in a high throughput rate.
Journal ArticleDOI
Thermoelectricity of near-resonant tunnel junctions and their relation to Carnot efficiency.
TL;DR: In this article, a conceptual study motivated by electrical and thermoelectrical measurements on various near-resonant tunnel junctions is presented, where the authors find the simplest and consistent description of the observed phenomena in the framework of the single level resonant tunneling model.
