Can we make a Salesforce Lightning Component that shows up in both the mobile and the desktop user interfaces?

Hi Chanchal,

You can use Lightning Components directly in Lightning Experience, the Salesforce1 Mobile app, template-based communities, and custom standalone apps. You can include Lightning components in a Visualforce page, allowing you to use them in Salesforce Classic, Console, and Visualforce-based communities.

Hi,

Lightning components were designed with Lightning Experience in mind. As the core Salesforce app shifts to the app-centric framework, we want you to shift along with us. We want you to think about developing on the platform in a whole new way.

You might have developed some Lightning components in Salesforce Classic. You can still use the old interface with Lightning components and all your existing component functionality transfers seamlessly into Lightning Experience.

So you can use Salesforce Lightning Component for both  mobile and the desktop user interfaces.

Hope this helps.
