Dissociative ionization and electron beam induced deposition of tetrakis(dimethylamino)silane, a precursor for silicon nitride deposition

Shih, Po-Yuan; Tafrishi, Reza; Cipriani, Maicol; Hermanns, Christian Felix; Oster, Jens; Gölzhäuser, Armin; Edinger, Klaus; Ingólfsson, Oddur (Royal Society of Chemistry (RSC), 2022-03-30)

Motivated by the use of tetrakis(dimethylamino)silane (TKDMAS) to produce silicon nitride-based deposits and its potential as a precursor for Focused Electron Beam Induced Deposition (FEBID), we have studied its reactivity towards low energy electrons ...
Electron beam induced deposition of silacyclohexane and dichlorosilacyclohexane: the role of dissociative ionization and dissociative electron attachment in the deposition process

T P, Ragesh Kumar; Hari, Sangeetha; Damodaran, Krishna Kumar; Ingólfsson, Oddur; Hagen, Cornelis W (Beilstein Institut, 2017-11-10)

We present first experiments on electron beam induced deposition of silacyclohexane (SCH) and dichlorosilacyclohexane (DCSCH) under a focused high-energy electron beam (FEBID). We compare the deposition dynamics observed when growing pillars of high ...
Electron interactions with the heteronuclear carbonyl precursor H2FeRu3(CO)13 and comparison with HFeCo3(CO)12: from fundamental gas phase and surface science studies to focused electron beam induced deposition

P, Ragesh Kumar T; Weirich, Paul; Hrachowina, Lukas; Hanefeld, Marc; Bjornsson, Ragnar; Hróðmarsson, Helgi Rafn; Barth, Sven; Fairbrother, D Howard; Huth, Michael; Ingólfsson, Oddur (Beilstein Institut, 2018-02-14)

In the current contribution we present a comprehensive study on the heteronuclear carbonyl complex H2FeRu3(CO)13 covering its low energy electron induced fragmentation in the gas phase through dissociative electron attachment (DEA) and dissociative ...
Electron-Transfer-Induced Side-Chain Cleavage in Tryptophan Facilitated through Potassium-Induced Transition-State Stabilization in the Gas Phase

da Silva, Filipe Ferreira; Cunha, Tiago; Rebelo, Andre; Gil, Adrià; Calhorda, Maria José; García, Gustavo; Ingólfsson, Oddur; Limão-Vieira, Paulo (American Chemical Society (ACS), 2021-03-25)

Fragmentation of transient negative ions of tryptophan molecules formed through electron transfer in collisions with potassium atoms is presented for the first time in the laboratory collision energy range of 20 up to 100 eV. In the unimolecular ...
Formation and decay of negative ion states up to 11 eV above the ionization energy of the nanofabrication precursor HFeCo3(CO)12

T P, Ragesh Kumar; Bjornsson, Ragnar; Barth, Sven; Ingólfsson, Oddur (Royal Society of Chemistry (RSC), 2017)

In single electron collisions with the heteronuclear metal carbonyl compound HFeCo3(CO)12 we observe the formation of long-lived negative ion states up to about 20 eV, 11 eV above its ionization energy. These transient negative ions (TNIs) relax through ...
Proton Shuttling and Reaction Paths in Dissociative Electron Attachment to o- and p-Tetrafluorohydroquinone, an Experimental and Theoretical Study

Ómarsson, Benedikt; Bjornsson, Ragnar; Ingólfsson, Oddur (American Chemical Society (ACS), 2017-07-21)

Here we present a combined experimental and theoretical study on the fragmentation of o- and p-tetrafluorohydroquinone upon low energy electron attachment. Despite an identical ring-skeleton and identical functional groups in these constitutional ...
