The rigid-layer mode shifts towards higher frequencies with an initial pressure coefficient of 0.234 GPa-1. The overall behavior is explained in terms of the volume anharmonicity characteristic of the van der Waals bonding. The internal bond-bending mode softens and the Born effective charge decreases linearly. By adopting the single-layer compressibility κl≃0.015 GPa-1 we obtain a Grüneisen parameter of -1.9 for the bond-bending mode and -0.55±0.05 for the effective charge, comparable to those of a tetrahedral semiconductor. Coexistence of such molecular and covalent characters leads to a nonlinear shift of the energy, Eg, of the Penn-Phillips oscillator. This behavior is shown to be described well by ΔEg=Da(Δa/a0) +Dc(Δc/c0) with the deformation potentials Da=-7.6±1.0 eV for the a axis and Dc=1.06±0.16 eV for the c axis. These deformation potentials reflect the dimensionality of bonding network as well as the nature of the electronic structure.","subitem_description_type":"Other"},{"subitem_description":"層状半導体の代表的な物質の１つとしてこれまで多くの関心を集めてきたGaSeについて、2次元的な化学結合の成り立ちと電子構造との関係を実験的に調べるために、ダイヤモンドアンビルセルを用いてラマン散乱スペクトルと光学屈折率の静水圧依存性を詳細に測定した。この実験によりGa-Se結合の有効電荷とs、p
