Sažetak

Difrakcijom elektrona pri prolazu kroz tanke slojeve titana (debljine od 10,9 do 113 nm) utvrđeno je da slojevi imaju polikristaliničnu strukturu. Relacija koja opisuje ovisnost otpora o debljini je podešavana za mjerenja na nekoliko raznih temperatura, i nađeno je da vrijedi Mayadas-Shatzkesova teorija. Nađeno je da su termički koeficijenti otpornosti pozitivni, te da srednji slobodni put vodljivih elektrona pada sa 44,19 na 21,43 nm kada temperatura raste od 308 do 463 K.
