Significant research has been aimed at making these normally insoluble materials into compounds that can be processed by solution methods. We report our approach to acene solubilization by careful consideration of how substituents affect the solid-state order of the materials. This change in native order leads to increases in conductivity, and in collaboration with the Jackson group has shown TFT mobilities >0.5 cm/sup 2//Vs from both vapor and solution. With this initial data in hand, we report our progress on second-generation materials designed to address the shortcomings of our initial compounds.","PeriodicalId":385948,"journal":{"name":"Conference Digest [Includes 'Late News Papers' volume] Device Research Conference, 2004. 62nd DRC.","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117127227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, metal-molecule-metal junctions have been widely studied. In this paper, charge transport through molecule-semiconductor junctions is considered. The presence of the energy band gap in semiconductors provides opportunities for resonant tunneling through individual molecules, leading to interesting effects such as negative differential resistance (NDR). Furthermore, by doping the substrate, the majority charge carrier can be tailored, thus allowing asymmetry to be intentionally designed into the current-voltage characteristic. Through judicious choice of the molecular species, the bias voltage of the NDR can also be controlled. By demonstrating these effects on the Si(100) surface, semiconductor-based molecular electronic devices have the potential of being directly interfaced to conventional silicon integrated circuit technology. This paper summarizes recent theoretical and experimental work on silicon-based molecular resonant tunneling diodes.","PeriodicalId":385948,"journal":{"name":"Conference Digest [Includes 'Late News Papers' volume] Device Research Conference, 2004. 62nd DRC.","volume":"09 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127312051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, we demonstrated independent double gate FinFETs, fabricated by using orientation-dependent wet etching. This method has great advantages in forming precise Si-fins with an atomically flat channel surface. In this paper, we present the successful fabrication of the ultra-thin Si-fins by wet etching, and the fine separated double gates. We show the excellent V/sub th/ controllability of the fabricated 4-T FinFETs by reducing the Si-fin thickness (T/sub Si/) down to 13 nm.

We create each molecular junction by separating two Au electrodes from contact in a solution containing the sample molecules. During the separation, we simultaneously measure the conductance and the force between the two electrodes. The conductance decreases in discrete steps, corresponding to the breakdown of individual molecules covalently bonded to the electrodes. Each discrete drop in the conductance is accompanied by a discrete drop in the force, which allows us to determine the bonding strength of the molecule to the electrodes. We have also determined the effective spring constant of a single molecule and the dependence of the conductance on the applied force.","PeriodicalId":385948,"journal":{"name":"Conference Digest [Includes 'Late News Papers' volume] Device Research Conference, 2004. 62nd DRC.","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115641174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Semiconductors on the other hand have poor piezoelectric and pyroelectric effects but have their abilities to show large change in conductivity with small bias. In this paper we examine the potential of devices based on heterostructures made from highly polar materials and semiconductors. Such functional devices have superior sensor properties as well as transistor properties. The basis device examined is based on the use of a thin oxide with high piezoelectric coefficients or pyroelectric coefficients under the gate region. Channel charge and current are directly controlled by gate voltage (normal FET), temperature (thermal sensor), or stress (stress sensor). We examine the performance of three classes of heterostructures that form the basis of important semiconductor technologies: (i) Si/SiO/sub 2//BaTiO/sub 3/ heterostructure junctions that would be an important breakthrough for silicon sensor technology; (ii) GaN/AlN/BaTiO/sub 3/ heterostructure junctions that would be important especially in high temperature sensor application; and (iii) GaAs/AlGaAs/BaTiO/sub 3/ heterostructure field effect transistors.","PeriodicalId":385948,"journal":{"name":"Conference Digest [Includes 'Late News Papers' volume] Device Research Conference, 2004. 62nd DRC.","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116726952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the mobility is the key factor in determining the device cut-off frequency, it is the purpose of this study to investigate the electron mobility improvement of SOI MESFET when compared to SOI and conventional MOSFET devices.
