Abstract
A method for bonding together two substrates includes providing a molecular glue including glue molecules, each of the glue molecules having at least two —O—Si or —O—Al moieties; reacting a surface of a first substrate with the molecular glue to attach the glue molecules to the surface of the first substrate by at least one of the —O—Si or —O—Al moieties; and reacting a surface of a second substrate with the molecular glue to attach the glue molecules to the surface of the second substrate by at least another one of the —O—Si or —O—Al moieties. The method can be used for a variety of applications including manufacturing a vapor cell.

A method for bonding together two substrates, the method comprising:
- providing a molecular glue comprising glue molecules, each of the glue molecules having at least two —O—Si or —O—Al moieties, wherein the glue molecules are selected from Al(OR)2—O-L-O—Al(OR)2 or Si(OR)3—O-L-O—Si(OR)3, wherein each R is independently hydrogen or C1 to C8 branched or unbranched alkyl and L is a linker group selected from C1 to C30 branched or unbranched alkylene or C6 to C30 cycloalkylene or C6 to C30 arylene;
- reacting a surface of a first substrate with the molecular glue to attach the glue molecules to the surface of the first substrate by at least one of the —O—Si or —O—Al moieties;
- and
- reacting a surface of a second substrate with the molecular glue to attach the glue molecules to the surface of the second substrate by at least another one of the —O—Si or —O—Al moieties.
A method for forming a vapor cell, the method comprising:
- providing a molecular glue comprising glue molecules, each of the glue molecules having at least two —O—Si or —O—Al moieties;
- reacting a surface of a first vapor cell substrate with the molecular glue to attach the glue molecules to the surface of the first vapor cell substrate by at least one of the —O—Si or —O—Al moieties;
- and
- reacting a surface of a second vapor cell substrate with the molecular glue to attach the glue molecules to the surface of the second vapor cell substrate by at least another one of the —O—Si or —O—Al moieties.
A vapor cell, comprising:
- a first substrate forming either a first cell wall or a first optical component;
- a second substrate forming either a second cell wall or a second optical component;
- and
- a molecular glue disposed between the first and second substrates and bonding the first and second substrates together, wherein a molecular glue comprises glue molecules, each of the glue molecules comprising at least two —O—Si or —O—Al moieties, wherein the —O—Si or —O—Al moieties form silicate or aluminate bonds to the first and second substrates.
