Adsorbed molecules in ALD arrange themselves so as to maximize their configurational entropy. Paper published in Chemistry of Materials!
Zhengning Gao's 'Standing and Sitting Adlayers in ALD of ZnO" shows us a new way to look at ALD surface reactions. A checkerboard based simulation shows adlayer entropy (or disorder) may play an important role.

High School students from the Youth Exploring Science (YES) Program at the St. Louis Science Center (SLSC) spent a day in our Nano Research Facility learning about electron microscopy and electronic chip fabrication
"Principles and Methods in Micro and Nanofabrication" is an experiential learning based lecture/lab series in the cleanroom facilities at Washington University. The course was launched for the first time in the Spring of 2013 by Prof. Banerjee.

Welcome to L.E.A.N.

The Laboratory for Emerging and Applied Nanomaterials (L.E.A.N.) at Washington University in St. Louis is involved in research of new and novel materials exploiting nature's ability to self-limit and self-assemble processes at the nano-level. We invite you to visit these pages and learn about exciting new developments in our lab.
