2017年4月1日 · In this paper, we report STM imaging and scanning tunnelling spectroscopy (STS) of different kinds of superlattices on HOPG characterized by a variation in lattice periodicities. Our study also shows evidence of the displacement of the topmost HOPG layer by scanning different areas of the same superlattice.

2005年6月7日 · Scanning tunneling spectroscopy (STS) measurements were made on surfaces of two different kinds of graphite samples, Kish graphite and highly oriented pyrolytic graphite (HOPG), at very low temperatures and in high magnetic fields.

2006年3月11日 · A combination of scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS) techniques have been performed on the wheel-shaped [Cu20Cl(OH)24(H2O)12(P8W48O184)]25- and the ball-sh...

In this paper, we present clear evidence for flat bands near Fermi energy in 1D extended defect on the surface of a highly oriented pyrolytic graphite (HOPG). A pronounced peak near Fermi energy...

2021年7月7日 · Here, we directly measured the density of states of a single monolayer of h-BN epitaxially grown on highly oriented pyrolytic graphite, by performing low temperature scanning tunneling microscopy (STM) and spectroscopy (STS). The observed h-BN electronic band gap on defect-free regions is (6.8 ± 0.2) eV.

2023年6月21日 · Here, using scanning tunneling microscopy and spectroscopy (STM/STS), we show the visualization and manipulation of single polarons in monolayer CoCl2, that are grown on HOPG substrate via ...

Highly oriented pyrolytic graphite (HOPG) is an important substrate in many technological applications and is routinely used as a standard in Scanning Tunnelling Microscopy (STM) calibration, which makes the accurate interpretation of the HOPG STM contrast of great fundamental and applicative importance. We demonstrate

1998年10月9日 · Ordered monolayers of the highly symmetric organic molecule coronene (C 24 H 12) have been deposited under ultrahigh vacuum conditions onto several atomically flat surfaces, such as HOPG (0001) and MoS 2 (0001). The adsorbates have been investigated by scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS).

2004年5月1日 · Abstract: Scanning tunneling spectroscopy measurements were made on surfaces of two different kinds of graphite samples, Kish graphite and highly oriented pyrolytic graphite (HOPG), at very low temperatures and in high magnetic fields. We observed a series of peaks in the tunnel spectra, which grow with increasing field, both at positive and ...

2012年9月18日 · In this study, a partially potassium-intercalated highly oriented pyrolytic graphite (K-HOPG) sample was prepared and the local electronic structure at the atomic level was examined with scanning...
