We review the pyroelectric properties and electronic structure of Li 2 B 4 O 7 (110) and Li 2 B 4 O 7 (100) surfaces. There is evidence for a pyroelectric current along the [110] direction of stoichiometric Li 2 B 4 O 7 so that the pyroelectric coefficient is nonzero but roughly 10 3 smaller than along the [001] direction of spontaneous polarization.

The four dopants (Nd, Gd, Dy, and Er) substitutionally occupy the Li + sites in lithium tetraborate (Li 2 B 4 O 7 : RE) glasses as determined by analysis of the extended X-ray absorption fine structure. The dopants are coordinated by 6-8 oxygen at a distance of 2.3 to 2.5 Å, depending on the rare earth. The inverse relationship between the RE-O coordination(More)
