A team of researchers from the University of South Florida and Florida State University has developed a one-pot synthesis technique for creating 2-D multi-junction heterostructures. In their paper published in the journal Nature, the team describes their technique and why they believe it will be useful for building future high-speed electronics and optoelectronic devices. Weijie Zhao and Qihua Xiong with Nanyang Technological University in Singapore offer a News and Views piece in the same journal issue outlining the work done by the team in Florida.
