Nature publishes exchange with Yu-Hao Deng re: TEMs and crystal planes in 2015 Nature paper “Quantum-dot-in-perovskite solids.” Posted on 9 June 2021 | by admin In today’s Nature please see a fruitful exchange with Yu-Hao Deng re: TEMs and crystal planes in our 2015 Nature paper “Quantum-dot-in-perovskite solids.” Deng’s letter stimulated us to redo the microscopy now using improved TEM equipment, and thus a much lower electron dose. The constructive exchange and updated experiments support the finding of dots in perovskite.
