Disorder increasingly affects performance as electronic devices are reduced in size. The ionized dopants used to populate a device with electrons are particularly problematic, leading to unpredictable changes in the behavior of devices such as quantum dots each time they are cooled for use. We show that a quantum dot can be used as a highly sensitive probe of changes in disorder potential and t...

Many of today's forefront materials, such as high-Tc superconductors, doped semiconductors, and colossal magnetoresistance materials, are structurally, chemically and/or electronically inhomogeneous at the nanoscale. Although inhomogeneity can degrade the utility of some materials, defects can also be advantageous. Quite generally, defects can serve as nanoscale probes and facilitate quasiparti...

To investigate the effect of Mn and other metal dopants on photoelectronic performance CsPbCl3 perovskites, we conducted a series theoretical analyses. Our findings showed that after mono-doping, lattice contracted bonding strength increased, resulting in more compact structure octahedral cage. The relaxation cage, along with Jahn–Teller effect, results decrease strain between octahedra reducti...

Understanding the effects of atomic structure modification in hematite photoanodes is essential for rational design high-efficiency functionalizations. Recently, it was found that interface with Sn/Sb segregates considerably increases photocatalytic efficiency. However, understanding different electronic these modifications at level still lacking. This Letter describes segregation two dopants–S...
