Piezo-modulated spectroscopic investigation of N and N-N Pairs in GaP

Пьезомодулированное спектроскопическое исследование N и N-N пар в GaP

Summary

We have investigated the effects of uniaxial compression along [001], [111] and [110] on the modulated-transmission spectra of an exciton bound to an isolated N as well as to N-N pairs. Our results show that the observed stress-induced splittings are associated with the valence band splitting, suggest that internal-strain effects may be significant for N and N-N pairs, and that the N-N pair interaction in weak.

Riassunto

Si sono analizzati gli effetti della compressione uniassiale lungo le direzioni [001], [111], [110] sugli spettri di trasmissione modulata di un eccitone legato a un N isolato o anche a coppie N-N. I nostri risultati mostrano che le separazioni indotte dallo sforzo che si osservano sono associate a separazioni della banda di valenza, suggeriscono che effetti di tensione interna possono essere rilevanti per N e per coppie N-N e che l’interazione tra coppie N-N è debole.

Резюме

Мы исследуем влияние неаксиального сжатия вдоль [001], [111] и [110] на модулированные трансмиссионные спектры экситона, связанного с изолированным N, а также с N-N парами. Наши результаты показывают, что наблюденные расщепления, индуцированные напряжением, связаны с расщеплением валентной зоны. Предполатается, что влияние внутренних напряжений может быть существенным для N и N-N пар и что взаимодействие N-N пар является слабым.
