It is composed of tin atoms arranged in a single layer, in a manner similar to graphene.{{Cite journal |last1=Xu |first1=Yong |last2=Yan |first2=Binghai |last3=Zhang |first3=Hai-Jun |last4=Wang |first4=Jing |last5=Xu |first5=Gang |last6=Tang |first6=Peizhe |last7=Duan |first7=Wenhui |last8=Zhang |first8=Shou-Cheng |date=2013-09-24 |title=Large-Gap Quantum Spin Hall Insulators in Tin Films |url=https://link.aps.org/doi/10.1103/PhysRevLett.111.136804 |journal=Physical Review Letters |language=en |volume=111 |issue=13 |pages=136804 |doi=10.1103/PhysRevLett.111.136804 |pmid=24116803 |issn=0031-9007|arxiv=1306.3008 |s2cid=11310025 }} Stanene got its name by combining stannum (the Latin name for tin) with the suffix -ene used by graphene.{{cite news | first = Ritu | last = Singh | url = https://zeenews.india.com/news/science/tin-could-be-the-next-super-material-for-computer-chips_892199.html | title = Tin could be the next super material for computer chips | work = Zeenews | date = November 24, 2013 }} Research is ongoing in Germany and China, as well as at laboratories at Stanford and UCLA.{{cite news |title=Designing the Next Wave of Computer Chips |url=http://www.nytimes.com/2014/01/10/science/designing-the-next-wave-of-computer-chips.html |date=January 9, 2014 |last=Markoff |first=John |work=New York Times |accessdate=January 10, 2014}}

The addition of fluorine atoms to the tin lattice could extend the critical temperature up to 100 °C.{{cite press release | url = https://www6.slac.stanford.edu/news/2013-11-21-tin-super-material-stanene.aspx | title = Will 2-D Tin be the Next Super Material? | publisher = SLAC National Accelerator Laboratory | location = Stanford University | date = November 21, 2013 }} This would make it practical for use in integrated circuits to make smaller, faster and more energy efficient computers.
