The original version of this Article contained an error in the Acknowledgements, which incorrectly omitted from the end the following: ‘J. Kang and L.W. Wang were supported by the Director, Office of Science, the Office of Basic Energy Sciences (BES), Materials Sciences and Engineering (MSE) Division of the U.S. Department of Energy (DOE) through the organic/inorganic nanocomposite program (KC3104) under contract DE-AC02-05CH11231. It used the computational resource of the Oak Ridge Leadership Computing Facility at the Oak Ridge National Laboratory through the INCITE project.’ This has been corrected in both the PDF and HTML versions of the Article.
