    • The electronic properties of molecular junctions of the general type carbon/molecule/TiO2/Au as examples of “molecular heterojunctions” consisting of a molecular monolayer and a semiconducting oxide. Junctions containing fluorene bonded to pyrolyzed photoresist film (PPF) were compared to those containing Al2O3 instead of fluorene, and those with only the TiO2 layer. The responses to voltage sweep and pulse stimulation were strongly dependent on junction composition and temperature. A transient current response lasting a few milliseconds results from injection and trapping of electrons in the TiO2 layer, and occurred in all three junction types studied. Conduction in PPF/TiO2/Au junctions is consistent with space charge limited conduction at low voltage, then a sharp increase in current once the space charge fills all the traps. With fluorene present, there is a slower, persistent change in junction conductance which may be removed by a reverse polarity pulse. This “memory” effect is attributed to a redox process in the TiO2 which generates TiIII and/or TiII, which have much higher conductance than TiO2 due to the presence of conduction band electrons. The redox process amounts to “dynamic doping” of the TiO2 layer by imposed electric field. The memory effect arises from a combination of the properties of the molecular and oxide layers, and is a special property of the molecular heterojunction configuration.
    • 作为由分子单层和半导体氧化物组成的“分子异质结”的一般类型的碳/分子/ TiO 2 / Au的分子连接的电子性质。 将含有与热解的光致抗蚀剂膜(PPF)结合的芴的接头与含有Al 2 O 3 O 3的芴代替芴进行比较,仅具有TiO 2 SUB>层。 对电压扫描和脉冲刺激的响应强烈依赖于结的组成和温度。 持续几毫秒的瞬态电流响应是由于TiO 2层中的电子的注入和捕获而产生的,并且发生在所研究的所有三种连接类型中。 在PPF / TiO 2 / Au结中的传导与低电压下的空间电荷限制传导一致,然后一旦空间电荷填充所有陷阱,电流就会急剧增加。 当存在芴时,会导致电阻较慢,持续的变化,这可能会被反极性脉冲除去。 这种“记忆”效应归因于TiO 2中的氧化还原过程,其产生具有高得多的Ti III和/或Ti II II 由于存在导带电子,导电性比TiO 2高。 氧化还原过程相当于通过施加的电场“TiO 2”层的“动态掺杂”。 记忆效应是由分子和氧化物层的性质的组合产生的,并且是分子异质结构型的特殊性质。

    • A query system (1600) is formed by a wizard (1605) operating to form a data server (1610) arranged to serve data from a data source (1615) to a client application (1630), each of the wizard, the client application, the data server and the data source being linked by a communications network (1650). The data source has native data types and data arranged in a data structure. The wizard operates to firstly identify the data source over the network. The wizard further provides an application program for traversing and examining at least one of the data structure and data of the identified data source. The application program is operable to generate a representative schema (1614) comprising mapping data for converting the native data types to predetermined data types of a common data model. The wizard further operates to create a server application (1612) adapted to use the representative schema to convert the data from the native data types to the predetermined data types and to serve the data to the client application according to the common data model over the network. The representative schema and the server application thereby form the data server generated by the wizard. Once formed, the data server may receive and respond to queries from the client application, which may have no knowledge of the native data types, but which are directed to the data source.
