Atomic Layer Deposition of Aluminum (111) Thin Film by Dimethylethylaminealane Precursor
Sameh Okasha, Yoshiaki Sekine, Satoshi Sasaki +1
We report the growth of aluminum (111) thin film by atomic layer deposition (ALD) technique with dimethylethylaminealane (DMEAA) as a precursor. It is found that the metallic under…
Coupling between Quantum Hall Edge Channels on Opposite Sides of a Hall Bar
Ngoc Han Tu, Masayuki Hashisaka, Takeshi Ota +4
We investigate the coupling between quantum Hall (QH) edge channels (ECs) located at opposite sides of a 50-um-wide Hall bar by exciting a charged wavepacket in one EC and detectin…
Quantum Hall effect in epitaxial graphene with permanent magnets
F. D. Parmentier, T. Cazimajou, Y. Sekine +5
We have observed the well-kown quantum Hall effect (QHE) in epitaxial graphene grown on silicon carbide (SiC) by using, for the first time, only commercial NdFeB permanent magnets…
Charge Fractionalization in Artificial Tomonaga-Luttinger Liquids with Controlled Interaction Strength
Paul Brasseur, Ngoc Han Tu, Yoshiaki Sekine +4
We investigate charge fractionalizations in artificial Tomonaga-Luttinger liquids (TLLs) composed of two capacitively coupled quantum Hall edge channels (ECs) in graphene. The inte…
Evaluation of Disorder Introduced by Electrolyte Gating through Transport Measurements in Graphene
Andrew Browning, Norio Kumada, Yoshiaki Sekine +3
We evaluate the degree of disorder in electrolyte gating devices through the transport measurements in graphene. By comparing the mobility in ion- and standard metal-gated devices,…
Bilayer-induced asymmetric quantum Hall effect in epitaxial graphene
Andrea Iagallo, Shinichi Tanabe, Stefano Roddaro +8
The transport properties of epitaxial graphene on SiC(0001) at quantizing magnetic fields are investigated. Devices patterned perpendicularly to SiC terraces clearly exhibit bilaye…
