We’re proud to an­nounce that GTS sci­en­tist José María González-Medina is a co-au­thor on a break­through pa­per be­ing pre­sent­ed next week at the IEEE In­ter­na­tion­al Re­li­a­bil­i­ty Phys­ics Sym­po­sium (IRPS 2026).

Bram Ver­yser from imec will pres­ent “Ter­man meth­od for thresh­old volt­age hys­tere­sis mod­el­ing with fixed in­ter­face charg­es of SiGe/Si/SiGe het­ero­struc­tures at cryo­gen­ic tem­per­a­tures” – re­search con­duct­ed in col­lab­o­ra­tion be­tween imec and KU Leu­ven as part of the EU-fund­ed ARC­TIC pro­ject (Ad­vanced Re­search on Cryo­gen­ic Tech­nol­o­gies for In­no­va­tive Com­put­ing).

At Global TCAD So­lu­tions, we’re hon­ored to have con­tributed to this work by pro­vid­ing Bram with our sim­u­la­tion soft­ware to mod­el the same SiGe/Si/SiGe het­ero­struc­tures that were ex­per­i­men­tal­ly char­ac­ter­ized. Through tech­ni­cal sup­port and ac­tive ex­change of ideas, we helped bridge the gap be­tween ex­per­i­men­tal mea­sure­ments and phys­ics-based sim­u­la­tion.

A graphical representation of the device, note that this is not to scale. The top 4 layers (incl. the QW) are in nm range while the bottom 3 are µm size.

This col­lab­o­ra­tion ex­em­pli­fies what we be­lieve TCAD should be: a tool that en­ables cut­ting-edge re­search and fos­ters mean­ing­ful sci­en­tif­ic ex­change. Un­der­stand­ing de­vice be­hav­ior at cryo­gen­ic tem­per­a­tures is crit­i­cal for emerg­ing quan­tum com­put­ing and ad­vanced com­put­ing ar­chi­tec­tures, and we’re proud that GTS Frame­work con­tributes to ad­vanc­ing this im­por­tant field.

Con­grat­u­la­tions to Bram Ver­yser and the en­tire re­search team at imec and KU Leu­ven on this ex­cel­lent work!
