For the samples corresponding to chemical composition with concentration of thallium 0.0025<x<0.005 double change of the sign of thermoelectric power is observed. In pure samples and samples with thallium concentration more than 1 at.% thermoelectric power it is positive in the whole temperature range. Various mechanisms which can lead to observable anomalies, including Kondo-like behavior of a nonmagnetic degenerate two-level system are discussed.

Essential elements of glass wet etching process such as: influence of glass composition, etching rate, influence of the residual stress in the masking layer, characterization of the main masking materials, the quality of surface generated using wet etching process are analyzed. As a result of this analysis an improved technique for deep wet etching of glass is proposed. A 500-/spl mu/m thick Pyrex glass wafer was etched through using a Cr/Au and photoresist mask, from our knowledge this is the best result reported. For an improved surface an optimal solution HF/HCl (10:1) was established for Pyrex and soda lime glasses.
