Journal ArticleDOI
Appropriate salt concentration of nanodiamond colloids for electrostatic self-assembly seeding of monosized individual diamond nanoparticles on silicon dioxide surfaces.
Taro Yoshikawa,Taro Yoshikawa,Verena Zuerbig,Fang Gao,René Hoffmann,Christoph E. Nebel,Oliver Ambacher,Oliver Ambacher,Vadim Lebedev +8 more
TL;DR: This major weakness of self-assembled diamond nanoparticles was solved by modifying the salt concentration of nanodiamond colloidal suspensions to suppresses the formation of small aggregates during the seeding process owing to the modified electrostatic repulsive interaction between nanoparticles.
Journal ArticleDOI
Electron spectro-microscopic determination of barrier height and spatial distribution of Au and Ag Schottky junctions on boron-doped diamond (001)
Shozo Kono,Hideyuki Kodama,Kimiyoshi Ichikawa,Taro Yoshikawa,Tadashi Abukawa,Atsuhito Sawabe +5 more
TL;DR: In this paper, the Schottky barrier heights (SBHs) and their spatial distribution for Au- and Ag-Schottky junctions fabricated on an acid-treated oxygen-terminated diamond (001) substrate were determined using X-ray photoelectron spectroscopy (XPS) core-level peaks.
Journal ArticleDOI
Analysis and optimization of sputter deposited AlN-layers for flexural plate wave devices
Markus Reusch,Katarzyna Holc,Wilfried Pletschen,Lutz Kirste,Agnė Žukauskaitė,Taro Yoshikawa,D. Iankov,Oliver Ambacher,Vadim Lebedev +8 more
TL;DR: In this article, the influence of process pressure and N2 concentration has been evaluated by means of spectroscopic ellipsometry, residual stress measurements, xray diffraction, atomic and piezoresponse force microscopy, along with analysis of the piezoelectric charge coefficient d33,f.
Journal ArticleDOI
Pinhole-free ultra-thin nanocrystalline diamond film growth via electrostatic self-assembly seeding with increased salt concentration of nanodiamond colloids
Taro Yoshikawa,Taro Yoshikawa,Fang Gao,Verena Zuerbig,Christian Giese,Christoph E. Nebel,Oliver Ambacher,Oliver Ambacher,Vadim Lebedev +8 more
TL;DR: In this article, the authors demonstrate the successful chemical vapor deposition of pinhole-free extremely thin (10−50nm) nanocrystalline diamond (NCD) films to examine the potential of electrostatic self-assembly seeding with increased salt concentration of nanodiamond colloids as a nucleation enhancement step.
Journal ArticleDOI
Straightforward synthesis of silicon vacancy (SiV) center-containing single-digit nanometer nanodiamonds via detonation process
Yuto Makino,Tomoaki Mahiko,Ming Liu,Akihiko Tsurui,Taro Yoshikawa,Shinji Nagamachi,Shigeru Tanaka,Kazuyuki Hokamoto,Masaaki Ashida,Masanori Fujiwara,Norikazu Mizuochi,Masahiro Nishikawa +11 more
TL;DR: In this article, the authors reported the successful synthesis of single-digit SiV-NDs via straightforward detonation process, which is known to have the high productivity in fabrication of singledigit NDs.
