Diamond and Polycrystalline Diamond for MEMSApplications :

To date most of the MEMS devices are been based on Silicon. This is due to the technological know-how accumulated on manipulating, machining, manufacturing of Silicon. However, only very few devices involve moving parts. This is because of the rapid wear arising from high friction in these Silicon based systems. Recent tribometric experiments carried out by Gardos on Silicon and polycrystalline...

Polycrystalline diamond films as prospective UV photocathodes

Polycrystalline diamond films grown by chemical vapor deposition have been considered recently for a number of UV detection applications. Negative electron affinity, chemical and mechanical stability and relative ease of fabrication make such films attractive candidates for effective and stable UV photoconverters. In this paper we present our study of the absolute quantum efficiency of a thin f...

Laser Raman Studies of Polycrystalline and Amorphic Diamond Films

This report describes the results of a number of different, but related, laser Raman studies on various CVD diamond samples. It attcmpts to show the versatility of Raman spectroscopy as a diagnostic tool for the quality of diamond films, by demonstrating its use in a few novel applications. The studies of the laser Raman spectra of amorphic diamond and CVD diamond films are performed using lase...

Attosecond dynamical Franz-Keldysh effect in polycrystalline diamond.

Short, intense laser pulses can be used to access the transition regime between classical and quantum optical responses in dielectrics. In this regime, the relative roles of inter- and intraband light-driven electronic transitions remain uncertain. We applied attosecond transient absorption spectroscopy to investigate the interaction between polycrystalline diamond and a few-femtosecond infrare...

Electron beam controlled restructuring of luminescence centers in polycrystalline diamond.

Color centers in diamond are becoming prime candidates for applications in photonics and sensing. In this work we study the time evolution of cathodoluminescence (CL) emissions from color centers in a polycrystalline diamond film under electron irradiation. We demonstrate room-temperature activation of several luminescence centers through a thermal mechanism that is catalyzed by an electron bea...
