WebApr 8, 2024 · Some insecurities I haven’t dealt with, yes. I’ll be the first to admit that I’m a lonely soul. And the last to admit I need a hand to hold. Losing hope, heading down a dangerous road. Strange, I know, but I feel most at home when I’m. Living in my agony. Watching my self-esteem go up in flames, acting like I don’t. WebThe small radius hole polarons (self-trapped holes (STH) known also as the V k centers) are very common color centers observed in numerous alkali halides and alkaline-earth halides. Their mobility controls the rate of secondary reactions between electron and hole defects and thus radiation stability/sensitivity of materials. We have analysed here the correlation …
