In doping and post-treatment effect on holographic properties in In:Ce:Cu:LiNbO3 crystal,张涛,徐玉恒,A series of triply-doped In:Ce:Cu:LiNbO3 crystals with a varying level of In doping were grown by Czochraski technique in air atmosphere, and some samples
Effect of dopants on magnetic properties of Cu-doped AlN nanorods,陈飞,季小红,The paper focuses on the influence of Cu doping on magnetic properties of Al1-xCuxN (0≤x≤0.05) nanorods. All AlN nanorods are highly textured in wurtzite structure with the c a
MySQL exists 和in 详解及区别
有一个查询如下:
SELECT c.CustomerId, CompanyName
FROM Customers c
WHERE EXISTS(
SELECT OrderID FROM Orders o
WHERE o.CustomerID = cu.CustomerID)
这里面的EXISTS是如何运作呢?子查询返回的是OrderId字段,可是外面的查询要找的是CustomerID和CompanyName字段,这两个字段肯定不在OrderI
Molybdenum (Mo) thin films, most commonly used as electrical back contacts in Cu(In,Ga)Se2 (CIGS) solar cells, are deposited by rf and dc magnetron sputtering in identical systems to study the discrepancy and growth mechanisms of the two sputtering t
Highly conducting ZnO:Al (AZO) films are normally prepared through substrate heating and post-annealing in reducing atmosphere, which is deleterious to maintain the high transparency of films and the overall so-lar cell performance. Here we fabricate
