This proposal was received in response to NSE, NSF-0019. The proposed research explores a new approach for increasing the density of logical operations in electronic circuits by using the polarization response of organic molecules. A key element of this approach is to use a Molecular Controlled SEmiconductor Resistor (MOCSER) to transduce the outcome of the logical operation into a current. Positive attributes of this scheme are less molecular decomposition, less severe statistical fluctuations and an ability to interface with today's microelectronics. The MOCSER is a specially designed and gateless metal-oxide semiconductor field effect transistor. In place of the metal gate on the transistor, organic molecules will be chemically bonded to the device's gate oxide. By polarizing these organic molecules the current flow between the source and drain electrodes of the transistor can be modulated. The work will begin by demonstrating the MOCSER's response to a voltage-controlled, molecular polarization. With the success of this initial phase of work the proposed effort will include two parts: nanolithography and demonstrating olecular templating. To demonstrate the feasibility of a 'solid-state' device a new generation of the MOCSER, in which the gate oxide region is connected to metal pads through a molecule, will be fabricated and tested. The nanolithography will be performed at the Cornell Nanofabrication Facility, in collaboration with the expertise from the Weizmann group . In parallel, we will use the templating of complementary DNA strands, one which is tethered to the gate region of the MOCSER and the other to the AFM tip, to characterize the self-assembly of molecules and voltage-controlled polarization response through noncovalent contacts. Successful completion of this work should set the stage for using molecular polarization to perform logic functions and transducing the molecular polarization into current in a solid-state electronic device.

该提案是根据NSE， NSF-0019收到的。本研究探索了一种利用有机分子的极化响应来增加电子电路中逻辑运算密度的新方法。这种方法的一个关键要素是使用分子控制半导体电阻器（MOCSER）将逻辑运算的结果转换成电流。该方案的积极特性是较少的分子分解，较少的严重统计波动以及与当今微电子技术相结合的能力。MOCSER是一种特殊设计的无栅金属氧化物半导体场效应晶体管。代替晶体管上的金属栅极，有机分子将被化学结合到器件的栅极氧化物上。通过使这些有机分子极化，晶体管的源极和漏极之间的电流可以被调制。这项工作将从展示MOCSER对电压控制的分子极化的反应开始。随着这一初步阶段工作的成功，拟议的努力将包括两个部分：纳米光刻和示范分子模板。为了证明“固态”器件的可行性，将制造和测试新一代MOCSER，其中栅极氧化区通过分子连接到金属衬垫。纳米光刻将在康奈尔纳米制造设施进行，与Weizmann小组的专业知识合作。同时，我们将使用互补DNA链模板，其中一条链连接到MOCSER的门区，另一条连接到AFM尖端，以表征分子的自组装和通过非共价接触的电压控制极化响应。这项工作的成功完成将为利用分子极化执行逻辑功能和在固态电子器件中将分子极化转化为电流奠定基础。
