Individual titanyl phthalocyanine(TiOPc)molecules on ultrathin sodium chloride striped films grown on Cu(110)exhibit two different topographies with 8-lobes and 6-lobes when imaged by scanning tunneling microscopy(STM...
Tomographic imaging and three-dimensional reconstruction based on a high-gain picosecond optical parametric amplifier (OPA) is demonstrated. More than 40dB intensity amplification of the image is achieved from the hig...
Ball-like nano-earbon thin films (BNCTs) are grown on Mo layers by microwave plasma chemical vapour deposition (MPCVD) system. The Mo layers are deposited on ceramic substrates by electron beam deposition method a...

We demonstrate the contrast reversal behaviour of topography artifacts by changing the diameter of the collection diaphragm in a transmission scanning near-field optical microscopy (SNOM). This originates from the c...
GaAs quantum dots(QDs)with high density and remarkable uniformity in dot size and distribution grown on Si(100)surface with artificial topography by radio-frequency sputtering have been demonstrated.The photoluminesce...

The spiral and ordina.ry dislocritions both running nearly perpendicular to the(001)growth surface of thallium acid phdiaJate,were revealed and identified by x-ray topography.They pinyunexpectedly important,role on th...
K_(o)-image of the Brazil twin boundary in quartz crystal by X-ray section topography and the same contrasts of the first fringes for entrance and exit surface are shown in this paper.
