通过磁阻和舒布尼科夫-德哈斯振荡研究了第5级氢化钠-石墨插层化合物的电子结构。石墨π电子载流子浓度低和层间载流子的缺乏，这与小费米能EF≈0.6eV有关，被认为是由NaH层间的强离子性引起的，与同结构氢化钾-石墨层间化合物的情况相反，该化合物在KH层间具有金属氢层，且石墨π载流子浓度高。
The electronic structure of stage 5 sodium hydride-graphite intercalation compounds is investigated by means of magnetoresistance and Shubnikov-de Haas oscillations. The small concentration of graphitic π electron carriers and the absence of intercalate carriers, which are related to the small Fermi energy EF≈ 0.6 eV, are considered to be brought about by the strong ionicity of the NaH intercalates, in contrast with the case of isostructural potassium hydride-graphite intercalation compounds which have metallic hydrogen layers in the KH intercalates with large concentration of graphitic π carriers.
