In some kinds of beta decay, a nuclide loses surplus positive charge by emitting a positron ( in the same event, a proton becomes a neutron, and neutrinos are also given off )
以某種貝它衰減,一個核素靠發出一個正電子失去剩餘正電荷(在相同的事件中,一個質子變成一個中子,而且也發射微中子) 。In 1987, a remarkable step was made by yablonovitch, who pointed out the possibility of the realization of photonic bandgaps, localized defect modes, and their applications to various optoelectronic devices, and by john who dicussed the strong localization of electromagnetic waves in disordered photonic crystals and also predicted many interesting quantum optical phenomena that can be realized in photonic crystals such as the bound state of photons and non - exponential decay of spontaneous emission
1987年yablonovitch和john開創性地提出光子晶體這一新概念, yablonovitch指出了有可能實現光子頻率帶隙和局域缺陷模以及許多光電技術方面的應用, john則討論了在無序光子晶體中電磁波的強烈局域現象,並預言在光子晶體中存在許多有趣的量子光學現象,諸如光子局域態、自發輻射的非指數衰減。
