Abstract

Monolayer Doping (MLD) involves the functionalization of semiconductor surfaces followed by an annealing step to diffuse the dopant into the substrate. We report an alternative doping method, oxide-MLD, where ultra-thin SiO2 overlayers are functionalized with phosphonic acids for doping Si. Similar peak carrier concentrations were achieved when compared to hydrosilylated surfaces (~2 × 1020 atoms/cm3). Oxide-MLD offers several advantages over conventional MLD such as ease of sample processing, superior ambient stability and minimal carbon contamination. The incorporation of an oxide layer minimizes carbon contamination by facilitating attachment of carbon-free precursors or by impeding carbon diffusion. The oxide-MLD strategy allows selection of many inexpensive precursors and therefore allows application to both p- and n-doping. The phosphonic acid functionalized SiO2 surfaces were investigated using XPS and ATR-FTIR spectroscopy while doping was assessed using electrochemical capacitance voltage and Hall measurements.

Attention Score in Context

This research output has an Altmetric Attention Score of 4. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 04 January 2018.
All research outputs
#6,317,064
of 21,075,379 outputs
Outputs from ACS Applied Materials & Interfaces
#3,193
of 15,322 outputs
Outputs of similar age
#146,503
of 440,107 outputs
Outputs of similar age from ACS Applied Materials & Interfaces
#88
of 361 outputs
Altmetric has tracked 21,075,379 research outputs across all sources so far. This one has received more attention than most of these and is in the 69th percentile.
So far Altmetric has tracked 15,322 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.6. This one has done well, scoring higher than 78% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 440,107 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 66% of its contemporaries.
We're also able to compare this research output to 361 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 75% of its contemporaries.
