Jaroszynski, J. (author), Popovic, D. (author), Klapwijk, T.M. (author)Studies of low-frequency resistance noise show that the glassy freezing of the two-dimensional electron system (2DES) in Si in the vicinity of the metal-insulator transition (MIT) persists in parallel magnetic fields B of up to 9 T. At low B, both the glass transition density ng and nc, the critical density for the MIT, increase with B such that...conference paper 2004
