  Sheet resistance of GaAs conductive layers isolated by proton irradiation

  摘要：

  A simple null charge model was employed to describe GaAs sheet resistance evolution as a function of proton implantation fluence using a previous knowledge of the irradiation created defect characteristics. In the specific case of GaAs irradiated with protons, three different irradiation related defect schemes were analyzed. Data obtained by both n-type and p-type majority carrier DLTS should be used together to give correct information about compensating deep centers. For a good estimation of isolation process by ion irradiation, not only the defects energy levels and introduction rates must be obtained, but also the corresponding charge transitions should be known.

We also demonstrate the first aldol reaction promoted by prebiotically-relevant proteinogenic amino nitriles (20 mol%) for the enantioselective synthesis of D-glyceraldehyde with 6% ee, and its subsequent conversion into

  了解形成DNA骨架的2-脱氧-D-核糖的益生元起源对于阐明生命起源至关重要，但仍需争论。在这里，我们证明了20 mol％的蛋白原性氨基酯比2-脱氧-D-苏糖戊糖促进2-脱氧-D-核糖的选择性形成，总产率≥4％。我们还证明了益生元相关蛋白原氨基腈（20 mol％）促进的第一个羟醛反应，用于对映体合成具有6％ee的D-甘油醛，随后转化为2-deoxy- D-核糖，产率≥5％。最后，我们在使用20 mol％的氨基酯或氨基腈促进剂的一锅法中探索了这两个步骤的组合。因此证明了三种星际起始物质，当与适当的促进剂混合在一起时，可以直接导致包括2-脱氧-D-核糖的高级碳水化合物的混合物的形成。
