2014 The correlation between the intrinsic luminescence of solid argon excited by slow electrons (a few eV to 100 eV) and desorption was studied. Related to exciton creation, a sharp threshold of desorption and of luminescence is observed at the same energy of the impinging electrons. The desorption rate is proportional to the exciton density at the surface. The surface nature of different lumi...

The effect of temperature on the electron-stimulated desorption lithium atoms from surface 2D semiconductor LixAuy intermetallic compounds in range 160 to 300 K was studied. were formed during deposition gold film 2 monolayers thick at room temperature. An island mechanism for formation has been proposed. decrease yield electronically stimulated with decreasing is associated a probability captu...

Tungsten hexacarbonyl (W(CO)(6)) is frequently used as an organometallic precursor to create metal-containing nanostructures in electron beam induced deposition (EBID). However, the fundamental electron stimulated reactions responsible for both tungsten deposition and the incorporation of carbon and oxygen atom impurities remain unclear. To address this issue we have studied the effect of 500 e...

The fundamental connection between electron stimulated desorption ~ESD! of hydrogen ~H!/ deuterium ~D! at silicon surfaces in ultrahigh vacuum and hot-carrier-stimulated desorption of H/D at the oxide/silicon interfaces in complementary metal–oxide–semiconductor ~CMOS! devices is presented. The dependences of device degradation on carrier energy and current density were studied on two generatio...

We report on Auger stimulated ion desorption via Coulomb explosion from surface self-assembled alkylthiol and fluorocarbon molecular layers, triggered by K-capture decay of an imbedded radioactive 55Fe atom. The charge state of the ejecta is determined by charge exchange in binary atomic collisions in bulk and electron tunneling outside the solid, as well as by fragmentation of electronically e...
