2008年1月17日 · Electron injection from the tip of a scanning tunnelling microscope (STM) has been used to stimulate local photon emission from the surface of a thin MgO film grown on Mo(001). Depending on the excitation energy, several emission regimes have been identified on the basis of the energy and the spatial distribution of the emitted photons.

2016年1月15日 · Using Auger electron spectroscopy, low electron energy diffraction and scanning tunneling microscopy/spectroscopy, we report here formation of MgO (1 x 1) and MgO (1 x 1)-R30 epitaxial layers, consistent with the growth of a MgO (111) polar film onto the silver surface and composed of patches having extended slight corrugation oriented along def...

2010年4月18日 · Here, we report an STM study of single water molecules on MgO (100)/Ag (100) combined with a first-principles density functional theory (DFT) calculation. By preparing MgO in the form of an...

2021年7月7日 · Atomic scale engineering of magnetic fields is a key ingredient for miniaturizing quantum devices and precision control of quantum systems. This requires a unique combination of magnetic stability...

2007年5月15日 · In this letter, we report on the photon emission from MgO thin films stimulated by electron injection from an Au tip. MgO is a prototype material for a wide band-gap insulator and should therefore exhibit optical activity originating from the radiative decay of excitons at low-coordinated surface sites [13].

2020年5月4日 · Electron injection from the tip of a scanning tunnelling microscope (STM) has been used to stimulate local photon emission from the surface of a thin MgO film grown on Mo(001). Depending on the excitation energy, several emission regimes have been identified on the basis of the energy and the spatial distribution of the emitted photons.

2014年12月1日 · In this study, we grew a thin MgO film on a Nb-doped SrTiO3 (STO) (100) single crystal, and studied the geometric and electronic structures with or without Fe nanoclusters using STM and scanning tunneling spectroscopy (STS). The STO (100) is an unique semiconducting substrate on which the epitaxial MgO films can be grown [11].

MgO ultrathin films are of great technological importance as electron tunneling barrier in electronics and spintronics, and as template for metallic clusters in catalysis and for molecular ...

2023年1月27日 · We investigate Er and Tm on MgO (100)/Ag (100) with x-ray absorption spectroscopy to address their magnetic and electronic properties and with scanning tunneling microscopy (STM) to identify their adsorption sites.

2007年6月27日 · Electroluminescence measurements have been performed with a scanning tunneling microscope (STM) to study the growth of Au particles on thin MgO films prepared on Mo(001). With increasing Au coverage, rapid quenching of the characteristic, defect-related MgO emission is observed, while a new peak emerges in the optical spectra that is attributed ...
