This projects deals with the first realization and fabrication of one-component diodes and one-component transistors which are planned to be utilized in light, gas and water splitting applications afterwards. We intend to synthesise and use pnp-switchable semiconductors like Ag18Cu3Te11Cl3 und AgCuS which show a reversible structural phase transition and an unique pnp switch of their semiconductor mechanism at this point. Goal of this project is to utilize this effect to create the first and former unseen one-component diode and one-component transistor which do not consist of two independent p- and n-type doped semiconductors, but which are generated by a simple thermal activation in a single material instead. Using U/I measurements on bulk and nano-materials we intend to determine the physical properties, the pn-transition kinetics and the electrical parameters of the diodes and transistors. Beside the known phases we will seek for new pnp-switchable materials and we intend to optimize the afore mentioned ones by substitution of cations and anions. Selected compounds will be tested for their potential in gas and light sensing applications and for water splitting. Here fore, we will measure the U/I characteristics upon application of gas or light or we test these materials as water splitting catalyst upon switching. Especially Ag18Cu3Te11Cl3 has an extraordinary potential with its pnp-switch at room temperature to be used in various applications. Recently, we were able to substantiate and publish the diode behaviour of Ag18Cu3Te11Cl3. The project is planned in close collaboration between two groups with competences in chemical material synthesis, nano chemistry, and crystal physics. After the termination of the project one-component diodes and transistors may be new players in IT technology, as sensors, or in manifold catalytic applications.

该项目涉及单组分二极管和单组分晶体管的首次实现和制造，计划随后用于光，气体和水的分解应用。我们打算合成和使用pnp开关半导体，如Ag 18 Cu 3 Te 11 Cl 3和AgCuS，它们在这一点上显示出可逆的结构相变和其半导体机制的独特pnp开关。该项目的目标是利用这种效应来创建第一个和以前看不见的单组分二极管和单组分晶体管，它们不是由两个独立的p型和n型掺杂半导体组成，而是由单一材料中的简单热激活产生的。使用U/I测量散装和纳米材料，我们打算确定的物理性质，pn-转变动力学和电参数的二极管和晶体管。除了已知的相，我们将寻求新的pnp开关材料，我们打算优化上述的阳离子和阴离子的替代。将测试选定的化合物在气体和光传感应用以及水分解方面的潜力。因此，我们将在应用气体或光时测量U/I特性，或者我们在切换时测试这些材料作为水裂解催化剂。特别是Ag_（18）Cu_（33）Te_（11）Cl_3在室温下具有pnp开关特性，具有广阔的应用前景。最近，我们能够证实并发表的二极管行为的Ag 18 Cu 3 Te 11 Cl 3。该项目计划在化学材料合成，纳米化学和晶体物理能力的两个小组之间密切合作。项目结束后，单组分二极管和晶体管可能成为IT技术的新参与者，如传感器或多种催化应用。
