Nevill Mott's Letter on Switching in Melanins

From Professor Sir Nevill Mott,frs

Oct 30

Dear Dr. McGinness

Your reprints are fascinating-- especially switching "in melanin", so like and yet so unlike the chalcogenide switches

On the latter, Adler, Heimsch & Mott (Rev. Mod. Phys. April 1978 ) represents my views---- but the model can hardly apply to melanin.

I have always hoped that these ideas will become of use in biology--- but doubt that the time has yet come. The next conference on amorphous materials is at Harvard ( Aug, 1978 ), organizer Prof W. Paul. Is it time for biological materials to make their debut there ?

Yours sincerely

Nevill Mott
