▼a Perovskites are a well-known class of materials with rich physics and a wide variety of applications. One such perovskite is tungsten oxide, which is a well-known chromogenic material used in smart windows and other display technologies. Due to |

▼a First, we examine alkali doping and incorporating the oxygen vacancy in cubic and monoclinic tungsten oxide. We investigate the relative stabilities of different charge states and its implications on electrical properties, such as conductivity a |
| 520 | |
▼a Next, we study the effect of charge doping. Tungsten trioxide has been experimentally shown to transform from the monoclinic symmetry to cubic symmetry with increasing monovalent doping. Our calculations show that electron doping primarily drive |

▼a Building on our insights on the electronic behavior of dopants and defects, we study the influence of doping concentration on transport. Understanding the transport properties of these carriers is critical in many of the device applications for |

▼a Finally, we examine the influence of doping concentration and structural distortions on optical absorption. We explore crystalline and disordered structures to demonstrate why these structural changes can enhance absorption at a microscopic leve |
