www.plasma-ald.com 2022 Year in Review


Introduction

The www.plasma-ald.com website hosts an easily searchable database of publications which discuss thin films derived from plasma enhanced atomic layer deposition.

The publication database currently has 1749 entries.

For each publication, numerous details of the plasma ALD usage are entered into the database to allow the publication to be found through various searches. The primary search categories include:

An advanced search page allows users to simulateously search on multiple criteria and narrow their search with additional publication details:

  • Deposition Temperature
  • Author Name and Affiliation
  • Characterization Analyses and Equipment
  • Substrate Material

This review reports on the website visitor volume in addition to the most popular searches and viewed pages on the website during 2022.

The information presented is derived from analyzing the web server logs with custom Python code utilizing the open source data analysis library, pandas. This analysis differs from last year which relied on Google Analytics data. Substantial efforts are made to remove all traffic not attributable to real visitors. To gain any trend insights, the 2021 data would need to be reanalyzed with the same code. I may get around to this eventually. There could be bugs in my code that impact the results. If I find any, I will fix them and update the review data if necessary.
