The Calendar 157-158On the Electrical Resistance of Thin Films.*BY ISABELLE STONE, PH.D.The investigation, as originally undertaken, was tofind the relation between the surface density and theresistance of thin films. The metal chosen was silverdeposited by the "Rochelle Salts process." The silverwas deposited on glass plates which were weighedbefore and after the silvering. From the weight ofthe silver and the dimensions of the glass plate thesurface density was calculated. The glass plates were8x.8 centimeters in dimensions and were laid facedownward in such a way that the ends rested on apacking of silver leaf over the copper terminals. Goodcontact between the glass and terminals was insuredby covers of fiber screwed down above and below theglass plates. Too great pressure which would break* Abstract of a thesis offered to the University in Candidacyfor the degree of Ph.D. in the Department of Physics,July 1897, by Isabelle Stone. the glass or tear the film was avoided by cushions ofpaper at either end of the covers. It was at oncenoticed that the resistance of the same film was notconstant but varied from hour to hour. Consecutivereadings showed a steady decrease in resistance, thefall being more marked, the higher the originalresistance.After it was discovered that the resistance of afilm at any time was a function of the age of the filman attempt was made to find out the rate of fall.Readings of the resistance of a new film were takenat intervals fifteen minutes apart for several hoursand consecutive readings taken on the same film afteran interval of sixteen or twenty-four hours. It wasfound that the greatest fall in resistance occurred inthe first twenty-four hours. Also, that the higher theoriginal resistance of the film, the greater the fall inthe first twenty-four hours.Experiments were tried to show the effect of heaton the films. It was found that heat accelerated thetime effect. A series of experiments was undertakento find how much heating was necessary to lower theresistance of a film to its minimum value, and ifless than this period of heating was allowed to seewhether the film continued to fall with time or not.Also at what point in the curve illustrating the fallof resistance with time the heat when applied wouldhave the greatest effect in lowering the resistance.It was discovered that, 1) heat accelerates the timeeffect ; 2) the greater the age of the film, the less theeffect produced on it by heat ; 3) in general, the longerthe heat is applied, the greater the fall in the resistance ; 4) a certain period of heating reduces theresistance of each film to its lowest value ; 5) this152 UNIVERSITY RECORDperiod of heating, necessary to produce the minimumresistance, is greater, the greater the initial value ofthe film ; 6) after the minimum resistance is reachedfurther heating has no effect upon the film ; 7) whennot reduced to its minimum resistance, by heat, thefilm continues to decrease with time in the ordinarymanner ; 8) when the lowest value of the resistance isproduced by heating, there seems to be a certainincrease in the resistance when measured after anumber of hours.It was decided to take films varying in initial resistance from 5 to 100,000 ohms, observe the resistancefrom day to day and construct curves for each film,taking times as abscissae and resistances as ordinates.Twelve covers of hard rubber were made for thetwelve films to be experimented upon. To prevent asulphide from forming on the films, fiber covers weresubsequently used. A new series of experiments wasundertaken, aiming to carry out three precautions,L) to avoid a sulphide formation, 2) to keep the film ati constant temperature, 3) to use the same silveringsolution for all the films. In one series of readings-,he films were placed in glass jars and kept in a felt-ined box in a constant-temperature room. For agreater precaution against the sulphide, they wereater placed in glass tubes from which the air wasifterward exhausted. By comparison of the resistance readings it was concluded that the age of theolution had to do with the fall of resistance, the fallq the first forty-eight hours being much less, the olderhe solution.Having drawn the curves given by the experimentalalues of the film at times when observations wereaken, the theoretical curve, to which each experi-lental curve most nearly corresponds, had to beeduced. The theoretical curve given by— fc/n2/=c1+c2e **>rresponded most closely with the experimentalirves, where clf c3, and k are constants whose valuesust be found for every curve and n a constant value.rom an observation of the curves and the values ofcorresponding to the curves, it is apparent that thewer the value of 7c, the slower the fall of resistance.In general, the decrease of resistance with time is/used by a gradual settling down of the silver mole-iles into a more and more compact mass. Heatcelerates this action, bringing in a few minutese film into that condition which time acting alonecomplishes only after months. Preliminary ex-riments indicate that electric currents and shocksoduce a similar effect upon a film as that producedheat.
