“…We confirmed that it corresponds to the previously reported "6"×5 phase with [11] a 1D structure along the 110 direction, using lowenergy-electron diffraction [ Fig. 1(e)] [32]. The STM and STS experiments were carried out using a commercial cryogenic STM (Unisoku, Japan) at 78 K. The bands structure of these nanowires were revealed by low temperature (~15 K) ARP measurements at an undulator beam line BL6U [33] of UVSOR synchrotron radiation facility (Okazaki, Japan) using photon energy (hν) of 46 ~ 80 eV and a standard hemispherical analyzer.…”

We investigated Pt-induced nanowires on the Si(110) surface using scanning tunneling microscopy (STM) and angle-resolved photoemission. High resolution STM images show a well-ordered nanowire array of 1.6 nm width and 2.7 nm separation. Angle-resolved photoemission reveals fully occupied one-dimensional (1D) bands with a Rashba-type split dispersion. Local dI/dV spectra further indicate well-confined 1D electron channels on the nanowires, whose density of states characteristics are consistent with the Rashba-type band splitting. The observed energy and momentum splitting of the bands are among the largest ever reported for Rashba systems, suggesting the Pt-Si nanowire as a unique 1D giant Rashba system. This self-assembled nanowire can be exploited for silicon-based spintronics devices as well as the quest for Majorana fermions.

“…As was described in ref. 18, at elevated temperatures and submonolayer coverages the surface undergoes a series of reconstruction depending on the amount of Pt. First, the ''16 Â 2'' reconstruction disappears changing to disordered Si(110) surface, then at $0:1 ML nanolines with stepped side walls decorated with Si pentagons start to develop and fill all the surface at $0:3 ML.…”

“…The study of submonolayer coverages of Pt on Si(110) has been carried out by scanning tunneling microscopy (STM) and had been published elsewhere. 18) In a present paper, we present results of scanning tunneling microscopy (STM) study of Pt silicide formation (more than one ML of Pt) on Si(110) surface.…”

A new algorithm for off-line computer optimization of radionuclide subtraction studies is presented. Within the digitized image, any region of interest may be chosen for the study. S o prior knowledge is required concerning the position and extent of the principal and interfering objects, nor concerning their image intensities. Tests show that even when statistical fluctuations are relatively large, the intensity quotient calculated by this algorithm is within one per cent of the correct value. A modified version of the algorithm may be used to estimate a uniform background and correct for its contribution. The effect of smoothing the images prior to the use of the algorithm has been investigated. The method has also been used for pancreas imaging and one example of this application is presented.

“…Despite the considerable attention for the 5d transition metal (Au, Pt, and Ir) induced NWs on Ge(001) [3][4][5][6]20], not much attention has been yet paid to the deposition of the these 5d transition metals on Ge(110). During the last decade several reports on the deposition of Dy, Co, Ag, Au, Pt, Gd, Y, Mn, Fe and Ir on the closely related Si(110) surface have appeared [21][22][23][24][25][26][27][28][29][30][31][32]. Visikovskiy and co-authors studied the Pt/Si(110) system and they found four different NW phases for coverages smaller than one monolayer (1 ML) [25], while for more than 1 ML Pt they reported the formation of 3D silicides [26].…”
