Electron dynamics of silicon surface states: second-harmonic hole burning on Si(111)-(7 x 7).

We report the first all-optical study of homogeneous linewidths of surface excitations by the spectral-hole-burning technique with surface-specific second-harmonic generation as a probe. Measurement of transient spectral holes induced by a 100 fs pump pulse in excitations of the surface dangling-bond states of Si(111)-(7 x 7) led to a pump-fluence-dependent homogeneous linewidth as broad as app...

The Effect of the Fractal Clusters on the Si (111)-7×7 Surface

one of the most important ingredients responsible for the success of integrated silicon technology is the Metal Oxide Semiconductor Field-Effect Transistor (MOSFET), and a major reason for its success is the MOSFET's scalability. Although the industry uses silicon and silicon dioxide in the electronic devices, it can be used for opto-electronic devices as well due to formation of fractal oxide ...

Paramagnetism of Si ( 111 ) - 7 × 7

Surface-sensitive second-harmonic generation, with the proper choice of symmetry, has demonstrated an extremely high sensitivity for detecting surface magnetization on Si(111)-7×7 induced by an external magnetic field of 10 T. Electron spins at the dangling bonds are suggested to be responsible for the observed magnetization of surfaces of nonmagnetic semiconductors. The temperature dependence ...
