Structural, electronic and magnetic properties of linear monoatomic chains adsorption on beryllium oxide nanotube: First-principle study

► All TM chains can be spontaneously adsorbed on the outer surface of BeONT. ► O site is the most stable adsorption site with the highest binding energies. ► Ti/BeONT and V/BeONT systems at O sites show half-metal character. ► TM chain adsorbed BeONT systems exhibit high magnetic moments.
