Growth and characterization of benzophenone and urea doped triglycine sulphate crystals

Structural and Optical Studies of Potential Ferroelectric Crystal: KDP Doped TGS

“…TGS has a major disadvantage that it is depolarized by thermal, mechanical, and electrical means. In order to overcome this difficulty, several studies have been attempted with different organic and inorganic dopants to achieve effective internal bias to stabilize the domains to increase the pyro electric and ferroelectric properties of TGS crystals [8][9][10][11][12][13][14].In this article, we report the effect of doping TGS crystal with potassium di hydrogen phosphate (KDP), and the characterization studies adopted for the grown crystal.…”

Growth and characterisation of l-threonine, dl-threonine and l-methionine admixtured TGS crystals

“…Many authors have investigated the effect of doping various amino acids like alanine, valine, etc. on TGS [2][3][4]. The effect of l-tyrosine and l-cystine on TGS crystal was reported by us earlier [5,6].…”

“…Triglycine sulfate ((NH 2 CH 2 COOH) 3 Á H 2 SO 4 : TGS) is a good ferroelectric material for the fabrication of IR detector. It has a second order phase transition at the Curie point.…”

Growth of thiourea-doped TGS crystals and their characterisation

“…The partial substitution of an optically active molecule in the place of glycine molecule causes an internal bias field, which causes the crystal permanently polarised [2][3][4]. In order to modify and improve properties for application, various dopants have been tried in TGS [5][6][7]. The effect of the amino acids l-tyrosine and l-cystine on TGS crystal was reported [8,9].…”
