Report

Enhancing the reactivity of Si(100)-Cl toward PBr3 by charging Si dangling bonds

Publikováno v: The Journal of Chemical Physics, 159, 214701 (2023)

The interaction of the PBr3 molecule with Si dangling bonds (DBs) on a chlorinated Si(100) surface was studied. The DBs were charged in a scanning tunneling microscope (STM) and then exposed to PBr3 directly in the STM chamber. Uncharged DBs rarely r

Dangling bonds on the Cl- and Br-terminated Si(100) surfaces

Autor: Pavlova, T. V., Shevlyuga, V. M., Andryushechkin, B. V., Eltsov, K. N.

Halogen monolayer on a silicon surface is attracting active attention for applications in electronic device fabrication with individual impurities. To create a halogen mask for the impurities incorporation, it is desirable to be able to remove a sing

Reactivity of the Si(100)-2$\times$1-Cl surface with respect to PH$_3$, PCl$_3$, and BCl$_3$: Comparison with PH$_3$ on Si(100)-2$\times$1-H

Autor: Pavlova, T. V., Eltsov, K. N.

Despite the interest in a chlorine monolayer on Si(100) as an alternative to hydrogen resist for atomic-precision doping, little is known about its interaction with dopant-containing molecules. We used the density functional theory to evaluate whethe

Ni-doped epitaxial graphene monolayer on the Ni(111) surface

Autor: Kovalenko, S. L., Pavlova, T. V., Andryushechkin, B. V., Zhidomirov, G. M., Eltsov, K. N.

Nickel-doped graphene has been synthesized from propylene on a Ni(111) surface and studied using scanning tunneling microscopy (STM) and density functional theory (DFT). It is established that nickel centers are formed during graphene synthesis on th

Hydrogen inserted into the Si(100)-2x1-H surface: A first-principles study

Autor: Pavlova, T. V.

An H atom inserted into hydrogen monolayer on the Si(100)-2x1 surface has been studied using the density functional theory. Hydrogen-induced defects were considered in their neutral, negative, and positive charge states. It was found that hydrogen at

Chlorine insertion and manipulation on the Si(100)-2x1-Cl surface in the regime of local supersaturation

Autor: Pavlova, T. V., Shevlyuga, V. M., Andryushechkin, B. V., Eltsov, K. N.

Publikováno v: Phys. Rev. B 101, 235410 (2020)

We insert and manipulate a single chlorine atom in chlorine monolayer on a Si(100)-2x1 surface using a scanning tunneling microscope. Two objects were created - a Cl atom in a groove between two dimer rows, and bridge-bonded Cl on a silicon dimer. Ch

Local removal of silicon layers on Si(100)-2x1 with chlorine-resist STM lithography

Autor: Pavlova, T. V., Shevlyuga, V. M., Andryushechkin, B. V., Zhidomirov, G. M., Eltsov, K. N.

Publikováno v: Applied Surface Science, 509 (2020) 145235

We report the realization of STM-based lithography with silicon layers removal on the chlorinated Si(100)-2x1 surface at 77 K. In contrast to other STM lithography studies, we were able to remove locally both chlorine and silicon atoms. Most of the e

Room temperature propylene dehydrogenation and linear atomic chain formation on Ni(111)

Autor: Pavlova, T. V., Kovalenko, S. L., Eltsov, K. N.

The structures formed by propylene adsorption on Ni(111) at room temperature are determined by a combination of scanning tunneling microscopy and density functional theory. As a result of the interaction with the Ni(111) surface, propylene molecules
