I just wonder why then so many research activities in silicon sensor structures to minimize the dark current. Like this one WO patent http://www.wipo.int/pctdb/en/wo.jsp?wo=2005083791

Any isolation should not make any effect to thermal noise as far as I can remember to my very much past phisics lessons.
