Where I need to create backend admin theme(vendor_name) in magento 2?

Question

I'm Getting Started in Magento 2. Here I created theme From app\design\frontend\Magento\<vendor_name>\<vendorname_modulename> it's working fine (under Vendor modules showing store front).

And I have created Adminhtml theme from app\design\adminhtml\<vendor_name>\<backend>\<vendorname_modulename> it's not working (under vendor modules from admin area).

Here I have a question.

Where I need to create backend admin Vendor_Theme?

Need to Create Vendor_Theme inside app\design\adminhtml\Magento\<backend>\<vendor_name>\<vendorname_modulename>?
