Defects and Dopants in CaFeSi₂O₆: Classical and DFT Simulations

Energies, 2020
Calcium (Ca)-bearing minerals are of interest for the design of electrode materials required for rechargeable Ca-ion batteries. Here we use classical simulations to examine defect, dopant and transport properties of CaFeSi2O6.

Single-Electron Transport through Single Dopants in a Dopant-Rich Environment [PDF]

Physical Review Letters, 2010
We show that single-electron transport through a single dopant can be achieved even in a random background of many dopants without any precise placement of individual dopants. First, we observe potential maps of a phosphorus-doped channel by low-temperature Kelvin probe force microscopy, and demonstrate potential changes due to single-electron trapping

Exact location of dopants below the Si(001):H surface from scanning tunnelling microscopy and density functional theory [PDF]

, 2017
Control of dopants in silicon remains the most important approach to tailoring the properties of electronic materials for integrated circuits, with Group V impurities the most important n-type dopants.

Reversing stealthy dopant-level circuits [PDF]

Journal of Cryptographic Engineering, 2014
A successful detection of the stealthy dopant-level circuit trojan, proposed by Becker et al. at CHES 2013 [1], is reported. Contrary to an assumption made by Becker et al., dopant types in active region are visible with either scanning electron microscopy SEM or focused ion beam FIB imaging.
