    • Characterizing the Metal–SAM Interface in Tunneling Junctions 

      Bowers, Carleen Morris; Liao, Kung-ching; Zaba, Tomasz; Rappoport, Dmitrij; Baghbanzadeh, Mostafa; Breiten, Benjamin; Krzykawska, Anna; Cyganik, Piotr; Whitesides, George McClelland (American Chemical Society (ACS), 2015)
      his paper investigates the influence of the interface between a gold or silver metal electrode and an n-alkyl SAM (supported on that electrode) on the rate of charge transport across junctions with structure Met(Au or ...

    • Fluorination, and Tunneling across Molecular Junctions 

      Liao, Kung-ching; Bowers, Carleen Morris; Yoon, Hyo; Whitesides, George McClelland (American Chemical Society (ACS), 2015)
      This paper describes the influence of the substitution of fluorine for hydrogen on the rate of charge transport by hole tunneling through junctions of the form AgTSO2C(CH2)n(CF2)mT//Ga2O3/EGaIn, where T is methyl (CH3) or ...

    • Introducing Ionic and/or Hydrogen Bonds into the SAM//Ga 2 O 3 Top-Interface of Ag TS /S(CH 2 ) n T//Ga 2 O 3 /EGaIn Junctions 

      Bowers, Carleen Morris; Liao, Kung-ching; Yoon, Hyo Jae; Rappoport, Dmitrij; Baghbanzadeh, Mostafa; Simeone, Felice C.; Whitesides, George McClelland (American Chemical Society (ACS), 2014)
      Junctions with the structure AgTS/S(CH2)nT//Ga2O3/EGaIn (where S(CH2)nT is a self-assembled monolayer, SAM, of n-alkanethiolate bearing a terminal functional group T) make it possible to examine the response of rates of ...

    • Molecular Series-Tunneling Junctions 

      Liao, Kung-ching; Hsu, Liang-Yan; Bowers, Carleen Morris; Rabitz, Herschel; Whitesides, George McClelland (American Chemical Society (ACS), 2015)
      Charge transport through junctions consisting of insulating molecular units is a quantum phenomenon that cannot be described adequately by classical circuit laws. This paper explores tunneling current densities in ...

    • Odd–Even Effects in Charge Transport across n -Alkanethiolate-Based SAMs 

      Baghbanzadeh, Mostafa; Simeone, Felice C.; Bowers, Carleen Morris; Liao, Kung-ching; Thuo, Martin; Baghbanzadeh, Mahdi; Miller, Michael S.; Carmichael, Tricia Breen; Whitesides, George McClelland (American Chemical Society (ACS), 2014)
      This paper compares rates of charge transport across self-assembled monolayers (SAMs) of n-alkanethiolates having odd and even numbers of carbon atoms (nodd and neven) using junctions with the structure MTS/SAM//Ga2O3/EGaIn ...

    • Rectification in Tunneling Junctions: 2,2′-Bipyridyl-Terminated n -Alkanethiolates 

      Yoon, Hyo Jae; Liao, Kung-ching; Lockett, Matthew R.; Kwok, Sen Wai; Baghbanzadeh, Mostafa; Whitesides, George McClelland (American Chemical Society (ACS), 2014)
      Molecular rectification is a particularly attractive phenomenon to examine in studying structure–property relationships in charge transport across molecular junctions, since the tunneling currents across the same molecular ...

    • Replacing \(Ag ^{TS} SCH_2-R\) with \(Ag^{TS}O_2C-R\) in EGaIn-Based Tunneling Junctions Does Not Significantly Change Rates of Charge Transport 

      Liao, Kung-ching; Yoon, Hyo; Bowers, Carleen Morris; Simeone, Felice; Whitesides, George McClelland (Wiley-Blackwell, 2014)
      This paper compares rates of charge transport by tunneling across junctions with the structures \(Ag^{TS}X(CH_2)_{2n}CH_3 //Ga_2O_3 /EGaIn \space\) (n=1–8 and \(X= -SCH_2-\) and \(O_2C-\)); here \(Ag^{TS}\) is template-stripped ...
