Term "growth per cycle" (GPC) gaining wider use

"Growth per cycle (GPC)" (unit e.g., nm) and "growth rate" (unit e.g., nm/cyc) have been described as alternative names to denote the time-independent amount of material deposited in a completed atomic layer deposition (ALD) cycle. The recent Baltic ALD 2016 conference confirmed the trend which I have noticed already earlier: the ALD community more and more shifts to use GPC.

I have been advocating the use of GPC since the early 2000s. A bit of history may be in place to explain why I chose to use GPC in the first place---how did it all get started? In the following, I will tell how one specific person has played a major role in the background.

History of ALD terminology: Growth per cycle (GPC)

Growth per cycle (GPC) is a term that is increasingly often used in ALD literature. Since when has it been used? Who has created it, or has it been created by many?

A discussion chain was just started in LinkedIn in the ALD - Atomic Layer Deposition group to find answers to these questions. Link to LinkedIn discussion chain: https://www.linkedin.com/groups/1885076/1885076-6122818578006757376. Your views appreciated!
