Publications

In the United States, publication is defined as:

the distribution of copies or phonorecords of a work to the public by sale or other transfer of ownership, or by rental, lease, or lending. The offering to distribute copies or phonorecords to a group of people for purposes of further distribution, public performance, or public display, constitutes publication. A public performance or display of a work does not of itself constitute publication.To perform or display a work "publicly" means –

(1) to perform or display it at a place open to the public or at any place where a substantial number of people outside a normal circle of a family and its social acquaintances is gathered; or

(2) to transmit or otherwise communicate a performance or display of the work to a place specified by clause (1) or to the public, by means of any device or process, whether the members of the public capable of receiving the performance or display receive it in the same place or in separate places and at the same time or at different times.

Grain boundary engineering in metavalent SnTe: A simplified approach

The metavalently bonded SnTe has gathered enormous attention recently as an environmentally friendly alternative to PbTe. While some of the issues with SnTe, including its small bandgap and large valence band offset, have largely been resolved, its relatively high lattice thermal conductivity (κl) has remained a matter of concern. Here, we show that the temperature-induced vacancy migration in SnTe results in the growth of SnTe nanoparticles in the intergrain region. The enhanced grain boundary scattering due to this led to a highly reduced κl and increased carrier mobility, enhancing the zT of our SnTe by almost 70% over the zT of various SnTe ingot samples from this and several previous studies. The validity of this approach was further confirmed for a 3% Ag-doped SnTe sample, a composition well-investigated in the past. The simplicity and effectiveness of our approach enhance the prospect of SnTe for practical applications.
